Create strong random passwords using cryptographically secure randomness, with custom length and character sets.
Everything runs locally in your browser
What does this tool do?
It generates random, strong passwords for your accounts using crypto.getRandomValues, a cryptographically secure random source. Everything runs locally and nothing is uploaded.
FAQ
Is the password saved or uploaded?
No. It is generated and shown only on this page, disappears on refresh, and is never sent to a server.
What counts as a strong password?
Usually 12+ characters mixing upper/lower/digits/symbols with no dictionary words. The tool shows a live strength estimate.
示例与注意事项Example & notes
一个例子A worked example
生成 16 位、含大小写字母+数字+符号的密码，一次给出多条候选，点其中一条即可复制使用。Generate 16-character passwords with upper and lower case, digits and symbols; several candidates are offered at once and one tap copies your pick.
注意事项Things to watch
- 随机数来自浏览器加密随机源（crypto.getRandomValues），不是 Math.random 这类可预测的伪随机。Randomness comes from the browser’s cryptographic source (crypto.getRandomValues), not the predictable Math.random.
- 密码只在你的浏览器里生成，不记录、不上传；刷新页面即消失。Passwords are generated locally, never logged or uploaded, and disappear when you reload.
- 重要账号建议 16 位以上、每个站点不重复，并配合两步验证。For important accounts use 16+ characters, never reuse across sites, and enable two-factor authentication.
相关问答More Q&A
生成的密码会被保存吗？Are generated passwords stored?
不会。页面没有账号体系也没有后端，关闭或刷新后结果不再存在。No. There is no account system and no backend; closing or reloading discards everything.
收藏夹存的密码和这里生成的有什么差别？How is this different from a password manager?
这里是生成器，不负责保管；长期使用建议把生成的强密码存进密码管理器。This is a generator, not a vault. Store the strong password it produces in a password manager.
