README

Ported from http://code.google.com/p/google-authenticator/

You can use the Google Authenticator app from here http://www.google.com/support/accounts/bin/answer.py?hl=en&answer=1066447 to generate One Time Passwords/Tokens and check them with this little PHP app (Of course, you can also create them with this).

Installation using Composer

composer require sonata-project/google-authenticator

Usage

See example.php for how to use it.

There's a little web app showing how it works in web/, please make users.dat writeable for the webserver, doesn't really work otherwise (it can't save the secret). Try to login with chregu/foobar.

What's missing in the example:

  • Prevent replay attacks. One token should only be used once
  • Show QR Code only when providing password again (or not at all)
  • Regenerate secret
