随机密码生成器 Random Password Generator

自定义密码长度与字符集，一键生成高强度随机密码，可批量生成多组密码，用于账号注册、系统登录与重要账户保护。
Customize length and character sets to generate strong random passwords, with optional batch generation for account signup, system login and sensitive account protection.

1. 输入参数 · Password Parameters
左侧为单个密码长度；右侧为一次生成多少个密码。
The left field is the length of each password; the right field is how many passwords to generate at once.
建议至少同时包含 大写 + 小写 + 数字，如再加上符号，可显著提升密码强度。
It’s recommended to include at least uppercase + lowercase + digits. Adding symbols can further increase password strength and resistance to brute-force attacks.
若勾选“符号”，但此处留空，则使用工具内置的默认符号集合。填写后将完全按你自定义的符号集合生成。
If “Symbols” is checked and this field is empty, a built-in default symbol set is used. If you provide your own symbols here, only these characters will be used for the symbol set.
3. 密码安全小贴士 · Password Security Tips
  • 长度优先，复杂度加持 · Prioritize length, then complexity:
    一般建议长度不少于 12 位，重要账号（邮箱、云盘、银行等）推荐 16–20 位以上，并搭配大小写字母、数字和符号。
    Use at least 12 characters, and for critical accounts (email, cloud storage, banking), 16–20+ characters with a mix of uppercase, lowercase, digits and symbols is recommended.
  • 不同网站用不同密码 · Use unique passwords per service:
    单个网站泄露时，若多个网站共用同一密码，就会引发“撞库”风险。通过随机密码 + 密码管理器，可以大幅降低连锁风险。
    If one website is breached, reused passwords can lead to “credential stuffing” on other services. Random passwords plus a password manager greatly reduce this risk.
  • 启用双重认证 · Enable 2FA when available:
    在支持的场景下，为重要账户开启短信验证码、TOTP 动态口令或硬件令牌，将密码泄露带来的风险再降一档。
    Whenever possible, enable SMS, TOTP apps or hardware tokens as a second factor to further reduce risk even if a password is compromised.
  • 避免可预测模式 · Avoid predictable patterns:
    不要用生日、手机号、简单序列（123456、qwerty）或含有明确个人信息的组合，即便长度够长，也很容易被针对性猜测。
    Avoid birthdays, phone numbers, keyboard sequences (123456, qwerty) or anything that reveals personal information, even if the password seems long.

说明：本工具仅在浏览器本地运行，密码生成逻辑完全在本地完成，不会上传到服务器或进行任何远程存储。 结果仅供学习与个人安全实践参考，请根据具体安全要求综合使用密码管理器与双重认证。
Note: All password generation happens locally in your browser; nothing is sent to any server. Use the results as part of your personal security practice together with password managers and multi-factor authentication.
