Google Authenticator PHP class
==============================

[](#google-authenticator-php-class)

[![Build Status](https://camo.githubusercontent.com/b84f394762ba1d051fd3b1c5b014a299046242fde6b8251e306d2377536e2a29/68747470733a2f2f7472617669732d63692e6f72672f52656e616e47616c656e6f2f504850476f6f676c6541757468656e74696361746f722e7376673f6272616e63683d6d6173746572)](https://travis-ci.org/RenanGaleno/PHPGoogleAuthenticator)

This PHP class can be used to interact with the Google Authenticator mobile app for 2-factor-authentication. This class can generate secrets, generate codes, validate codes and present a QR-Code for scanning the secret.

For a secure installation you have to make sure that used codes cannot be reused (replay-attack).

Usage:
------

[](#usage)

See example files

```
php example1.php
Secret is: OQB6ZZGYHCPSX4AK

Google Charts URL for the QR-Code: https://www.google.com/chart?chs=200x200&chld=M|0&cht=qr&chl=otpauth://totp/infoATphpgangsta.de%3Fsecret%3DOQB6ZZGYHCPSX4AK

Checking Code '848634' and Secret 'OQB6ZZGYHCPSX4AK':
OK

```
