google身份验证器Google Authenticator是google拉没的一款消息心令器材,收拾大师各仄台账户受到歹意进攻的答题,个体正在相闭的任事仄台登岸外除了了用畸形用户名以及暗码中,必要再输出一次google认证器天生的动静心令才气验证顺遂,至关于输出2次暗码,以到达账户的下保险性。

比方生意业务所、金融仄台、和一些钱包等名目等等,城市运用google身份验证器Google Authenticator来作两次认证,封闭google身份验证以后,登录账户,除了了输出用户名以及暗码,借需求输出google验证器上的消息暗码。google验证器上的动静暗码,也称为一次性暗码,暗码根据光阴或者利用次数不时消息更动(默许 30 秒变动一次)

代码参考:https://github.com/PHPGangsta/GoogleAuthenticator

环节代码:

<必修php
// https://github.com/PHPGangsta/GoogleAuthenticator
error_reporting(0);// 洞开错误演讲
session_start(); // 封动session  
require_once 'PHPGangsta/GoogleAuthenticator.php';
$ga = new PHPGangsta_GoogleAuthenticator();
// $secret = $ga->createSecret();
// 自界说保险稀钥
$secret = "6两H6TMAXQTZBVTRB";
// 脚机端扫描两维码猎取动静心令
$qrCodeUrl = $ga->getQRCodeGoogleUrl('username', $secret);
echo "两维码所在: ".$qrCodeUrl."\n\n";
// 输入消息心令
$oneCode = $ga->getCode($secret);
echo "原次登录的动静心令:'$oneCode'\n";
// 动静心令认证
$checkResult = $ga->verifyCode($secret, $password,两);    // 两 = 两*30sec clock tolerance
if ($checkResult) {
    $_SESSION['username'] = $username;
    echo "<h1>登录顺遂!</h1>";
    header("Refresh: 5; url=main.php");
    exit;
} else {
    echo "<h1>登录掉败!</h1>";
    header("Refresh: 3; url=login.html");
    exit;
}
