在线密码生成器的优势
- Privacy. Passwords are generated in the browser. Nothing is sent to the server, so only you can see them.
- Free, no sign-up. Open the page and use it. No account, email, or app install required.
- Flexible settings. Choose length and any mix of digits, lowercase, uppercase, and symbols.
- Strength meter. See entropy in bits and estimated crack time for the current settings.
- Task presets. Wi-Fi, shell, PIN, URL, and dictation — one click.
- Shareable settings link. Copy the URL and open the same options elsewhere — the password never goes in the link.
- No duplicates. Turn on “no duplicates” so repeats are limited (unique up to length 61; at most twice above that).
- One-click copy. Click a password to copy it to the clipboard.
- Readable output. Ambiguous characters (I, O, l, |) can be excluded, so passwords are easier to retype or read aloud.
- Service-friendly. Symbols are kept out of the first and last two characters, so forms, shells, and scripts are less likely to reject the password.
- Fast and light. Works on desktop and mobile, with many languages.
如何在线生成密码
- Set the password length with the “−” and “+” buttons.
- Select the character sets you need: digits, lowercase, uppercase, symbols.
- Optionally enable “no duplicates”.
- Press Generate.
- Click a password to copy it, then save it in a password manager.
怎样的密码才算强
Password strength depends on length and character variety. Simple words, birth dates, names, and sequences like 123456 or qwerty are cracked in seconds. A random generated password avoids those patterns.
建议：
- Use at least 12–16 characters. For admin accounts and servers, 20+ is better.
- Combine lowercase, uppercase, digits, and symbols.
- Use a unique password for every service.
- Store passwords in a password manager, not in notes or messengers.
- Enable two-factor authentication wherever you can.
- Change a password if you suspect a leak.

常见问题
Is it safe to generate a password online?
Yes. The password is created locally in your browser and is not sent to the server, so the site cannot intercept or store it.
Is the generator free?
Yes. The service is free, with no registration and no limit on how many passwords you create.
What password length should I choose?
For everyday accounts, 12–16 characters is a good range; for important services and servers, use 20 or more.
Why are I, O, l, and | excluded?
They are easy to confuse with 1, 0, and each other. Without them, passwords are easier to read and type by hand.
Why aren’t symbols placed at the start or end?
Some systems mishandle edge symbols when copying, in shells, or in config files. Keeping edges alphanumeric makes the password work more reliably.
What does “no duplicates” mean?
Up to length 61 each character appears only once; above 61, at most twice. Handy when a service limits repeats.
Do I need to memorize the generated password?
No. Save it in a password manager and use autofill.
How is password strength calculated?
The meter scores generation settings (length and alphabet), not a specific string, and shows entropy in bits.
What are entropy and bits?
Entropy estimates the search space: more bits means a longer crack time under the same attack model.
How do I share generator settings?
Use Copy link: the address holds settings only — never the password itself.
Why exclude characters?
If a service forbids some symbols or you need to read the password aloud, remove the awkward characters from the alphabet.
