!!! Be careful when you upgrade your multiOTP open source Virtual Appliance !!! The multiOTP open source Virtual Appliance is using the files in raspberry/boot-part/multiotp-tree/usr/local/bin/multiotp, with config and backend folders defined to be located in /etc/multiotp/
If you are currently using the multiOTP open source Virtual Appliance, you can upgrade
the multiOTP version by copying the extracted content of the folder and subfolders from
raspberry/boot-part/multiotp-tree/usr/local/bin/multiotp to /usr/local/bin/multiotp
An update through the web interface should be available in the future
If you are currently using the multiOTP open source linux files, you can upgrade your installation by copying the extracted content of the folder and subfolders from linux to your current multiOTP folder
!!! since 5.0.4.6 under Linux, the config, devices, groups, tokens and users folders are now always located in /etc/multiotp/. Please be sure to make the move when you are upgrading !!! (before 5.0.4.6, theses subfolders where located just below the main multiOTP folder)
If you are currently using the multiOTP open source windows files, you can upgrade your installation by copying the extracted content of the folder and subfolders from windows to your current multiOTP folder

Specific parameters order in QRCode for Microsoft Authenticator support
(thanks to Erik Nylund)
2013-12-23 4.1.0 The open source edition of multiOTP is OATH certified ;-)
(that means full compatibility with any OATH tokens and encrypted PSKC import support)
Raspberry Pi nanocomputer is now fully supported
Basic web interface
Self-registration of hardware tokens is now possible
PAP mode: if self-registration is enabled, a user can register a non-attributed token by typing
[serial number][OTP] instead of [OTP]. If user has a prefix PIN, type [serial number][PIN][OTP])
PAP/CHAP mode: if self-registration is enabled, a user can register a non-attributed token by typing
[username:serialnumber] as the username and the [OTP] in the password field.
If user has a prefix PIN, [PIN][OTP] must be typed in the password field
Automatic resync/unlock option during authentication (PAP only). When the autoresync option
is enabled, any user can resync his token by typing [OTP1] [OTP2] in the password field.
If user has a prefix PIN, he must type [PIN][OTP1] [PIN][OTP2].

A typical installation has the following tree organization:
Software files
/usr/local/bin/
/usr/local/bin/multiotp (contains multiotp.php)
/usr/local/bin/multiotp/templates
Data files
/etc/multiotp/
/etc/multiotp/config (contains multiotp.ini)
/etc/multiotp/devices
/etc/multiotp/groups
/etc/multiotp/tokens
/etc/multiotp/users (contains my_user1.db, my_user2.db, ...)
The multiotp.php file is a copy of the multiotp.cli.header.php including the copy of all files that are included in the PHP code, which are multiotp.class.php and the whole contrib subfolder content.
For the virtual appliance and the Raspberry Pi edition, the multiotp.php file is a copy of the multiotp.cli.proxy.php file. (the proxy version calls the multiotp.proxy.php using the web server, and the web server has a PHP cache to improve the speed of the whole process).
For the virtual appliance and the Raspberry Pi edition, the multiotp.proxy.php file is a copy of the multiotp.cli.header.php including the copy of all files that are included in the PHP code, which are multiotp.class.php and the whole contrib subfolder content.
For the virtual appliance and the Raspberry Pi edition, the following line in multiotp.class.php
$multiotp = new Multiotp('DefaultCliEncryptionKey', $initialize_backend, $folder_path);
is replaced by
$multiotp = new Multiotp('DefaultCliEncryptionKey', $initialize_backend, $folder_path);
if (false !== strpos(getcwd(), '/')) {
$multiotp->SetConfigFolder('/etc/multiotp/config/');
$multiotp->SetCacheFolder('/tmp/cache/');

If you decide to have strong two factor authentication inside your company, this is definitely the package you need! You will be able to have strong authentication for your VPN accesses, your SSL gateway, your private websites and even your Windows login for desktops AND laptops!
The multiOTP class can be used alone (for example to have strong authentication for your PHP based web application), as a command line tool (to handle users and have strong authentication using command line), as a web service (to provide centralized authentication for a client/server installation) or finally coupled with a radius server like TekRADIUS or FreeRADIUS to be able to have a strong two factor authentication through the RADIUS protocol for external devices like for example firewalls or captive portals.
The default backend storage is done in flat files, but you can also defined a MySQL server as the backend server. To use MySQL, you will only have to provide the server, the username, the password and the database name. Tables will be created/updated automatically by multiOTP. The schema is also upgraded automatically if you install a new release of multiOTP.
Starting with version 4.x, you can also install a multiOTP web service on a server, and this way some other multiOTP slave clients (like laptops) can connect to the web service and caching the tokens information (if allowed).
Inside a company, you will probably use multiOTP with a radius server or as a web service (see below on how to install these services).
If you are running under Windows, TekRADIUS or TekRADIUS LT will do the job (http:/www.tekradius.com/). The difference is that TekRADIUS needs an MS-SQL SERVER (or MS-SQL Express) and TekRADIUS LT uses only an embedded SQLite database.
multiOTP is working fine under Windows with WinRADIUS, a port of FreeRADIUS (http://winradius.eu/)
multiOTP is also working fine with another port of FreeRADIUS for Windows (http://sourceforge.net/projects/freeradius/)
If you are running under Linux, FreeRADIUS will do the job. (http://freeradius.org/)
Now, you can register your different devices like firewalls, SSL, etc. in the radius server and provide the IP address(es) of the device(s) (often called NAS) and their shared Secret.
If you want to have strong authentication on Windows logon, have a look at the
open source multiOTPCredentialProvider which is based on MultiotpCPV2RDP from
arcadejust and MultiOneTimePassword Credential Provider from Last Squirrel IT.
It works with Windows 7/8/8.1/10/2012(R2)/2016 in both 32 and 64 bits.
The Credential Provider does not need any RADIUS connection! It uses instead a
local version of multiOTP which can be configured as a client of a
centralized server (with caching support).
(http://download.multiotp.net/credential-provider/)
LSE Experts provides a commercial Radius Credential Provider which can talk directly with a radius server. (http://www.lsexperts.de)
When the backend is set, it's time to create/define the tokens. You will have to select hardware or software token generators for your users. Currently, the library supports mOTP, TOTP, HOTP, SMS or scratch passwords (printed on paper).
mOTP is a free implementation of strong tokens that asks a PIN to generate a code. This code depends of the time and the PIN typed by the user.
A special without2FA token type is also available. It could be useful to do 2FA only for some accounts and not for others.
The easiest tokens to use are TOTP, they are time based and well supported by a lot of implementations like Google Authenticator. Provisioning will be done simply by flashing a QRcode.

If you want to use software tokens with Apps like Google Authenticator, you can create a QRcode provisioning in two EASY steps with the command line tool:
- create the token for the user (without prefix PIN request): multiotp -fastcreatenopin my_user
- generate the provisioning QRcode: multiotp -qrcode my_user my_qrcode.png
You can also create a user quickly with the prefix PIN request option based on the default option set in your configuration: multiotp -fastcreate my_user
And of course, you can also force to create a user quickly with a requested prefix PIN: multiotp -fastcreatewithpin my_user
The prefix PIN option is activated by default. Users will have to type their PIN + the displayed token. The prefix PIN option has no effect for mOTP tokens, and the users MUST NOT type their prefix PIN before the displayed token for mOTP tokens, as the prefix PIN is already used by the algorithm in order to generate the token.
Starting with version 4.3, it's now possible to use the synchronized AD/LDAP password as a prefix instead of the static PIN. Please note that even with the AD/LDAP password as a prefix activated, the PIN used for mOTP tokens is still the static PIN.
To create a user quickly with the prefix PIN request option based on the default option set in your configuration: multiotp -fastcreate my_user
To create a user quickly without a prefix PIN request: multiotp -fastcreatenopin my_user
To create a user quickly with a requested prefix PIN: multiotp -fastcreatewithpin my_user
To prevent brute-force attack, an account is temporary locked for 300 seconds
after 3 unsuccessful trials.
After 6 unsuccessful trials, the account is definitely locked.
A user is unlocked by typing the following command line: multiotp -unlock user
A user can also unlock his account by typing two consecutive codes,
separated by a space (don't forget the prefix PIN/password if enabled).
If prefix PIN is enabled, your PIN is 1234 and the two consecutive tokens are
984501 and 348202, you will have to type "1234984501 1234348202" as the
password in order to unlock the account during authentication.
The lockout parameters can be modified using these command lines:
multiotp -config failure-delayed-time=60
multiotp -config max-block-failures=12
multiotp -config max-delayed-failures=10
In order to have debug information, you can use the -debug option. With this
option, the debug information are saved in the file log/multiotp.log.
If you want to see directly the debug information on screen, add the
-display-log and an output of the debug information will be done on screen too.
In order to enable the debug mode permanently without using the option, you can do that like this: multiotp -config debug=1
The same thing can be done for a permanent display of the debug information on the screen without using the option: multiotp -config display-log=1
Installing the multiOTP web service is VERY easy. Simply run the webservice_install script. Nginx configuration file will be created, firewall rules will be adapted and the service will be installed and started. The service is called multiOTPservice and is listening on port 8112 (http) and on port 8113 (https).
Installing the multiOTP radius service is VERY easy too. Simply run the radius_install script. The etc/raddb/modules/multiotp file will be created, firewall rules will be adapted and the service will be installed and started. The service is called multiOTPradius and the secret is multiotpsecret for any client including 127.0.0.1.
TekRADIUS supports a Default Username to be used when a matching user profile cannot be found for an incoming RADIUS authentication request. So a quick and easy way is to create in the TekRADIUS Manager a User named 'Default' that belongs to the existing 'Default' Group. Then add to this Default user the following attribute : Check External-Executable C:\multitop\multiotp.exe %ietf|1% %ietf|2% -chap-challenge=%ietf|60% -chap-password=%ietf|3% -ms-chap-challenge=%msoft|11% -ms-chap-response=%msoft|1% -ms-chap2-response=%msoft|25%
Some values can go back to TekRADIUS:
a) Set the right format options for TekRADIUS: multiotp -config radius-reply-attributor="=" radius-reply-separator="crlf"
b) Set multiOTP to send back to TekRADIUS the clear (non encrypted) authentication: multiotp -config clear-otp-attribute="ietf|2"
c) Set multiOTP to send back to TekRADIUS the group of the authenticated user: multiotp -config group-attribute="ietf|11"
The multiOTP web service is a simple web site. If you are under Linux and you are reading this document, you have for sure the necessary skill to configure your favorite web server in order to have an URL that will launch the page multiotp.server.php which is in the main folder of the multiOTP distribution.
Please check carefully the rights of the folders, as the multiOTP web service has to write in the various subfolders.
Using the -request-nt-key option, NT_KEY: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX can now be displayed (like with the same option used with ntlm_auth).
- Create a new module file called "multiotp" in etc/raddb/modules/ containing:
# Exec module instance for multiOTP (http://www.multiotp.net/).
# for Linux : replace '/path/to/multiotp' with the actual path to the multiotp.php file, including the full file name.
# for Windows: replace '/path/to' with the actual path to the multiotp.exe file (also with /), including the fulle file name.
exec multiotp {
wait = yes
input_pairs = request
output_pairs = reply
program = "/path/to/multiotp '%{User-Name}' '%{User-Password}' -request-nt-key -src=%{Packet-Src-IP-Address} -chap-challenge=%{CHAP-Challenge} -chap-password=%{CHAP-Password} -ms-chap-challenge=%{MS-CHAP-Challenge} -ms-chap-response=%{MS-CHAP-Response} -ms-chap2-response=%{MS-CHAP2-Response}"
shell_escape = yes
}
- In the configuration file called "default" in etc/raddb/sites-enabled/
a) Add the multiOTP handling
#
# Handle multiOTP (http://www.multiotp.net/) authentication.
# This must be added BEFORE the first "pap" entry found in the file.
multiotp
b) Add the multiOTP authentication handling
#
# Handle multiOTP (http://www.multiotp.net/) authentication.
# This must be added BEFORE the first "Auth-Type PAP" entry found in the file.
Auth-Type multiotp {
multiotp
}
c) Comment the first line containing only "chap"
#chap is now handled by multiOTP
d) Comment the first line containing only "mschap"
#mschap is now handled by multiOTP
-
In the configuration file called "inner-tunnel" in etc/raddb/sites-enabled/
a) Add the multiOTP handling
#
# Handle multiOTP (http://www.multiotp.net/) authentication.
# This must be added BEFORE the first "pap" entry found in the file.
multiotp
b) Add the multiOTP authentication handling
#
# Handle multiOTP (http://www.multiotp.net/) authentication.
# This must be added BEFORE the first "Auth-Type PAP" entry found in the file.
Auth-Type multiotp {
multiotp
}
c) Comment the first line containing only "chap"
#chap is now handled by multiOTP
d) Comment the first line containing only "mschap"
#mschap is now handled by multiOTP
- In the configuration file called "policy.conf" in etc/raddb/
Add the multiOTP authorization policy
#
# Handle multiOTP (http://www.multiotp.net/) authorization policy.
# This must be added just before the last "}"
multiotp.authorize {
if (!control:Auth-Type) {
update control {
Auth-Type := multiotp
}
}
}
-
In the configuration file called "radiusd.conf" in etc/raddb/
Depending which port(s) and/or ip address(es) you want to listen, change the corresponding ipaddr and port parameters -
In the configuration file called "clients.conf" in etc/raddb/
Add the clients IP, mask and secret that you want to authorize.
#
# Handle multiOTP (http://www.multiotp.net/) for some clients.
client 0.0.0.0 {
netmask = 0
secret = multiotpsecret
}
-
Now, to see what's going on, you can:
- stop the service : /etc/init.d/freeradius stop
- launch the FreeRADIUS server in debug mode : /usr/sbin/freeradius -X
- try to make some authentication requests
-
When you have checked that everything works well:
- stop the debug mode (CTRL + C)
- restart the service /etc/init.d/freeradius restart
Some values can go back to FreeRADIUS:
a) Set the right format options for FreeRADIUS:
multiotp -config radius-reply-attributor=" += " radius-reply-separator=","
b) Set multiOTP to send back to FreeRADIUS the group of the authenticated user:
multiotp -config group-attribute="Filter-Id"
Source: https://wiki.freeradius.org/guide/multiOTP-HOWTO
multiOTP tokens will work with any type of PAP/CHAP/MS-CHAP/MS-CHAPv2 based authentication, including EAP-TTLS-PAP. With the correct OS/Supplicant software tokens can be used for 802.1X authentication and well as for standard PAP/CHAP/MS-CHAP/MS-CHAPv2 authentication (just make the changes described in the inner server). This guide closely follows the NTLM Auth with PAP HOWTO but with a little extra validation.
NT_KEY generation is also supported using the -request-nt-key option (like for ntlm_auth --request-nt-key option), which is needed in order to enable VPN (PPTP + MPPE) with MS-CHAP/MS-CHAPv2.
Before starting or asking for help
- Make sure the otp script is executable chmod +x /path/to/multiotp.php
- Verify multiotp is setup correctly by calling the script from the commandline with the appropriate arguments
- Create 'raddb/modules/multiotp' and add the following, this will create a new instance of the exec module:
# Exec module instance for multiOTP
# Replace '/path/to' with the actual path to the multiotp.php file
exec multiotp {
wait = yes

- Edit 'raddb/policy.conf' and add the following to override the authorize method of the exec module: (or add a new multiotp file in the policy.d folder) policy {
# Change to a specific prefix if you want to deal with normal PAP authentication as well as OTP
# e.g. "multiotp_prefix = 'otp:'"
multiotp_prefix = ''
multiotp.authorize {
# This test force multiOTP for any MS-CHAP(v2) attempt
if (control:Auth-Type == MS-CHAP) {
update control {
Auth-Type := multiotpmschap
}
}
# This test force multiOTP for any MS-CHAP(v2) attempt
elsif (control:Auth-Type == mschap) {
update control {
Auth-Type := multiotpmschap
}
}
# This test force multiOTP for any CHAP attempt
elsif (control:Auth-Type == chap) {
update control {
Auth-Type := multiotp
}
}
# This test is for decimal OTP code only, otherwise you will have to change it
# elsif (!control:Auth-Type && User-Password =~ /^${policy.multiotp_prefix}([0-9]{10})$/) {
#
# Use this simple test for non decimal only OTP code: elsif (!control:Auth-Type) {
#
# This test force multiOTP for any other attempt like PAP
elsif (!control:Auth-Type) {
update control {
Auth-Type := multiotp
}
}
}
}
-
Edit your virtual server file, the default for the outer server is 'raddb/sites-available/default'
-
Add a call to multiotp before the pap module in authorize:
authorize {
...
# Handle multiotp authentication
multiotp
# Handle other PAP authentication
pap
...
}
- Create the multiotp sub-section in authenticate:
authenticate {
Auth-Type multiotp {
multiotp
}
Auth-Type multiotpmschap {
multiotpmschap
}
}
- Start the server up in debug mode radiusd -X and test authentication

DON'T FORGET TO SCHEDULE A SCRIPT THAT WILL DO THE USERS SYNCHRONIZATION REGULARY!
A) On the server
- Install the multiOTP web service on the authentication server side. If you are using the unmodified included installer to install it under Windows, the URL for the multiOTP web service is http://ip.address.of.server:8112 The web service script installer is called webservice_install.cmd.
- Set the shared secret key you will use to encode the data between the server and the client: multiotp -config server-secret=MySharedSecret (this command line will change the configuration file config/multiotp.ini)
- If you want to allow the client to cache the data on its side, set the options accordingly (enable the cache and define the lifetime of the cache): multiotp -config server-cache-level=1 server-cache-lifetime=15552000 (this command line will change the configuration file config/multiotp.ini)
- Create your users on the server using the CLI or the web GUI interface. If you are using the unmodified included installer to install it under Windows, the URL for the multiOTP web service is http://ip.address.of.server:8112
B) On the client(s)
- Set the shared secret key you will use to encode the data between the client and the server: multiotp -config server-secret=MySharedSecret (this command line will change the configuration file config/multiotp.ini)
- If you want to have cache support (if allowed by the multiOTP web service), set the option accordingly: multiotp -config server-cache-level=1 (this command line will change the configuration file config/multiotp.ini)
- Define the timeout after which you will switch to the next server(s), and on the local cache if no server available: multiotp -config server-timeout=3 (this command line will change the configuration file config/multiotp.ini)
- Last but not least, define the server(s) you want to connect with: multiotp -config server-url=http://ip.address.of.server:8112;http://url2 (this command line will change the configuration file config/multiotp.ini) If you want to connect with a commercial multiOTP appliance, the URL is https://ip.address.of.commercial.multiotp.server
- Check your installation on the client by typing multiotp -display-log -log -debug "user" "token", where "user" is an existing user and "token" is the generated token for this user. If you have created a user with a prefix PIN, don't forget to type the prefix PIN before the displayed token. Example without a prefix PIN: multiotp test 457863 Example with the "1234" prefix PIN: multiotp test 1234457863
- Install multiOTPCredentialProvider, which contains also multiOTP inside. It works with Windows 7/8/8.1/10/2012(R2)/2016 in both 32 and 64 bits. (http://download.multiotp.net/credential-provider/)
- During the installation, specify the folder on the client where the multiotp.exe file and folders must be installed and configured.
- In the wizard, leave the URL of the multiOTP server(s) empty.
- You can also choose to require a strong authentication only for RDP.
- When you are on the test page, open a command prompt in the folder where multiOTP is now installed and create a new local user as explained above.
- If the test is successful, the Credential Provider is installed.
- To disable the Credential Provider, uninstall it from Windows, or execute multiOTPCredentialProvider-unregister.reg
HOW TO INSTALL A CENTRALIZED STRONG AUTHENTICATION SERVER FOR STRONG AUTHENTICATION ON WINDOWS DESKTOPS OR RDP ?
- Install a client/server multiOTP environment like explained above.
- On each client, install multiOTPCredentialProvider . It works with Windows 7/8/8.1/10/2012(R2)/2016 in both 32 and 64 bits. (http://download.multiotp.net/credential-provider/)
- During the installation, specify the folder on the client where the multiotp.exe file and folders must be installed and configured.
- In the wizard, type the URL of the multiOTP server(s).
- You can also choose to require a strong authentication only for RDP.
- On the test page, test your account to be sure that everything works.
- If the test is successful, the Credential Provider is installed.
- To disable the Credential Provider, uninstall it from Windows, or execute multiOTPCredentialProvider-unregister.reg
- If you want to download a multiOTP Raspberry Pi image ready to use, follow this URL:
http://download.multiotp.net/raspberry/
Nano-computer name: multiotp
IP address: 192.168.1.44 (netmask: 255.255.255.0, default gateway: 192.168.1.1)
Username: pi
Password: raspberry
You can now flash the SD (check point 3) and 4) if needed), put the SD Card into the Raspberry Pi and boot it. You can go directly to point 15)
-
If you want to use a battery backed up Real Time Clock, install it now in your Raspberry Pi, the drivers for these models are included in the package:
-
Download the last image of Raspbian to be flashed
http://downloads.raspberrypi.org/raspbian_latest (currently 2017-09-07-raspbian-stretch.zip) -
Format your SD Card using the SD Card Association's formatting tool
https://www.sdcard.org/downloads/formatter_4/ -
Flash the raw image using UNIX tool dd or Win32DiskImager for Windows (http://sourceforge.net/projects/win32diskimager/files/latest/download).
This should take about 10 minutes. -
Copy all files from multiotp/raspberry/boot-part to the root of the SD Card
(it could overwrite some files like config.txt) -
When copy is done, eject the SD Card
-
Connect the Raspberry Pi to the local network
-
Put the SD card into the Raspberry Pi and boot it
-
Login directly on your Raspberry Pi, or using SSH, with the default username "pi" and the password "raspberry"
-
Launch the initial configuration by typing sudo raspi-config
-
Choose the following options
- Expand Filesystem
- Change User Password
- Internationalisation Options (if needed)
- Advanced Options
A2 Hostname (change the hostname to your favorite name, for example "multiotp")
-
Select Finish and answer "" to reboot, ore type "sudo reboot"
-
Login again directly (after about 30 seconds) on your Raspberry Pi, or using SSH, with the default username "pi" and your new password
-
Type "sudo /boot/install.sh"
Everything is done automatically (it will take about 35 minutes) and the Raspberry Pi is rebooted automatically -
The fixed IP address is set to 192.168.1.44, with a default gateway at 192.168.1.1
To adapt the network configuration, edit the file /etc/network/interfaces -
Congratulations! You have now an open source and fully OATH compliant strong two factors authentication server!
Surf on http(s)://192.168.1.44 to use the basic interface (admin / 1234) -
The default radius secret is set to myfirstpass for the subnet 192.168.0.0/16.
To adapt the freeradius configuration, edit the file /etc/freeradius/clients.conf.
You can define how the certificate bundle is handled with the ldaptls_reqcert option. You can define a custom cipher suite with the ldaptls_cipher_suite option.
Open source multiOTPCredentialProvider, based on MultiotpCPV2RDP and mOTP-CP
If you want to have strong authentication on Windows logon, have a look at the
open source multiOTPCredentialProvider.
It works with Windows 7/8/8.1/10/2012(R2)/2016 in both 32 and 64 bits.
The Credential Provider is using directly a local version of multiOTP which
can be configured as a client of a centralized multiOTP server (with caching support)
(https://github.com/multiOTP/multiOTPCredentialProvider)
LSE Experts is providing a commercial Radius Credential Provider which can talk directly with any radius server to check the token. multiOTP will work with it. (http://www.lsexperts.de)
Any firewall can connect with the Radius protocol to a multiOTP radius server. On advanced firewalls like the ZyXEL ZyWALL USG series, you can do some advanced things like:
- receiving a specific group for each multiOTP user (using the Filter-Id option). This is very useful to allow specific rules for some groups.
- VPN connections can be set-up to have a strong authentication (X-Auth).
- Strong Web authentication can be combined with specific firewall rules.

multiOTP 5.6.1.5 (2019-10-23)
(c) 2010-2019 SysCo systemes de communication sa
http://www.multiOTP.net (you can try the [Donate] button ;-)
multiotp will check if the token of a user is correct, based on a specified
algorithm (currently Mobile-OTP (http://motp.sf.net), OATH/HOTP (RFC 4226)
and OATH/TOTP (RFC 6238) are implemented). PSKC format supported (RFC 6030).
Supported encryption methods are PAP and CHAP.
Yubico OTP format supported (44 bytes long, with prefixed serial number).
SMS-code are supported (current providers: aspsms,clickatell,clickatell2,
intellisms,nexmo,nowsms,smseagle,swisscom,custom,exec).
Specific SMS sender program supported by specifying exec as SMS provider.
Google Authenticator base32_seed tokens must be of n*8 characters.
Google Authenticator TOTP tokens must have a 30 seconds interval.
Available characters in base32 are only ABCDEFGHIJKLMNOPQRSTUVWXYZ234567
To quickly create a user, use the -fastcreate option with the name of the user.
A quickly created user is compatible with Google Auth (30 seconds, 6 digits).
Depending on the prefix PIN option (WHICH IS ENABLED BY DEFAULT), a prefix PIN
will be requested or not before the displayed token.
If the PIN is not given, it is generated randomly.
To quickly create a user without a prefix PIN request, use -fastcreatenopin
To quickly create a user with a prefix PIN request, use -fastecreatewithpin
If a token is locked (return code 24), you have to resync the token to unlock.
Requesting an SMS token (put sms as the password), and typing the received
token correctly will also unlock the token.
The check will return 0 for a correct token, and the other return code means:
Return codes:
0 OK: Token accepted

multiOTP can be combined with a Raspberry Pi (http://www.raspberrypi.org/) in
order to have a very low budget strong authentication device. Please look at
the readme file in order to learn how to set it up in a few steps.
The distribution is already optimized with an HTTP proxy to speed up the CLI.
A ready to use binary image can be downloaded at http://download.multiotp.net/
multiOTP open source is also available as a ready to use virtual appliance in
standard OVA, VMware optimized or Hyper-V formats.
Virtual appliance images can be downloaded at http://download.multiotp.net/
