如何修复多个临时登录后的未知登录

// 示例代码：密码强度检查
function checkPasswordStrength(password) {
    const strongRegex = /^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,}$/;
    return strongRegex.test(password);
}

// 示例代码：启用2FA
const speakeasy = require('speakeasy');
const QRCode = require('qrcode');

// 生成密钥
const secret = speakeasy.generateSecret({ length: 20 });

// 生成二维码
QRCode.toDataURL(secret.otpauth_url, (err, data_url) => {
    console.log(data_url);
});

// 验证2FA
const verified = speakeasy.totp.verify({
    secret: secret.base32,
    encoding: 'base32',
    token: '用户输入的验证码'
});

// 示例代码：记录登录日志
const fs = require('fs');

function logLoginAttempt(username, success) {
    const logEntry = `${new Date().toISOString()} - ${username} - ${success ? 'Success' : 'Failed'}\n`;
    fs.appendFile('login.log', logEntry, (err) => {
        if (err) throw err;
    });
}

# 示例命令：更新Node.js包
npm update
