two-factor-auth

golang implementation for google two-factor-auth

comments added from the original repo: github.com/robbiev/two-factor-auth

Simple CLI app that generates tokens compatible with Google Authenticator. I implemented this mainly to understand how it works, you should probably not use this.

Example output:

$ go run main.go "<your key>"
