README

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.

Requirements

Optionally, you may need:

sockets if you are using NTPTimeProvider
endroid/qr-code if using EndroidQrCodeProvider or EndroidQrCodeWithLogoProvider.
bacon/bacon-qr-code if using BaconQrCodeProvider.
php-curl library when using an external QR Code provider such as QRServerProvider, ImageChartsQRCodeProvider, QRicketProvider or any other custom provider connecting to an external service.

The best way of installing this library is with composer:

php composer.phar require robthree/twofactorauth

For a quick start, have a look at the getting started page or try out the demo.

If you need more in-depth information about the configuration available then you can read through the rest of documentation.
