The Auth0 redirect protocol enables many advanced authentication scenarios, specifically ones that require additional user interaction beyond the standard login form. It's most commonly used to do custom MFA (multifactor authentication) in Auth0, but it can serve many other purposes, like:
- Custom privacy policy acceptance, terms of service, and data disclosure forms
- Securely performing a one-time collection of additional required profile data
- Allowing remote Active Directory users to change their password (see example)
This directory contains examples of using the redirect protocol in various ways, including MFA. And if you'd just like a simple example that you can easily run within your Auth0 account, check out the Simple Example with a Webtask rule.
