Google Authenticator + base64 qrcode PHP class
==============================================

[](#google-authenticator--base64-qrcode-php-class)

谷歌的两步验证PHP服务端，Google身份验证器 Google Authenticator PHP实现，自带二维码生成类库， 再也不用担心服务端密码泄露问题了！

PS: 本工具为安全类工具，$secret 为本工具安全的基础， 如果$secret 泄露，则本工具失去安全的意义！ 网上其他类似工具使用的第三方API生成二维码的方式是极不安全的！！！

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. It implements TOTP according to [RFC6238](https://tools.ietf.org/html/rfc6238)

For a secure installation you have to make sure that used codes cannot be reused (replay-attack). You also need to limit the number of verifications, to fight against brute-force attacks. For example you could limit the amount of verifications to 10 tries within 10 minutes for one IP address (or IPv6 block). It depends on your environment.

Usage:
------
