Thread:Extension talk:TwoFactorAuthentication/Problems.../reply

I installed it and after fixing the require as you noted and realizing you need to do a database update (I updated the extension page), it does display the QR code and I am able to successfully scan it. However, when I provide the code back to enable there is a PHP error which results in the page not rendering:

PHP message: PHP Notice: Undefined property: SpecialTwoFactorAuth::$TwoFactorUser in .../TwoFactorAuthentication/SpecialTwoFactorAuth.php on line 168 PHP message: PHP Fatal error: Call to a member function verifyToken on a non-object in .../TwoFactorAuthentication/SpecialTwoFactorAuth.php on line 168

Would love to get this working, but so far no luck. WikiApiary does show some use of this extension, but only a couple of sites.
