PHP library for two-factor (or multi-factor) authentication using TOTP and QR-codes. Inspired by, based on but most importantly an improvement on 'PHPGangsta/GoogleAuthenticator'. There's a .Net implementation of this library as well.
- Tested on PHP 5.6 up to 8.0
- cURL when using the provided
QRicketProviderbut you can also provide your own QR-code provider.
- random_bytes(), MCrypt, OpenSSL or Hash depending on which built-in RNG you use (TwoFactorAuth will try to 'autodetect' and use the best available); however: feel free to provide your own (CS)RNG.
Optionally, you may need:
- sockets if you are using
- endroid/qr-code if using
- bacon/bacon-qr-code if using
The best way of installing this library is with composer:
php composer.phar require robthree/twofactorauth
