Uppercase (A–Z) Lowercase (a–z) Numbers (0–9) Symbols (!@#…)

Composition Guarantees

Ensure the generated password always contains at least one of each selected type.

Min. 1 Uppercase ? Guarantees at least one uppercase letter (A–Z) appears in the password. Min. 1 Lowercase ? Guarantees at least one lowercase letter (a–z) appears in the password. Min. 1 Number ? Guarantees at least one digit (0–9) appears in the password. Min. 1 Symbol ? Guarantees at least one symbol (!@#$…) appears in the password.

Extra Options

Exclude Similar (i, l, 1, O, 0) ? Avoids characters that can be confused, such as I, l, 1, O, and 0. Exclude Ambiguous ({ } [ ] ( )…) ? Avoids symbols that may be difficult to read or enter, such as {}, [], and (). Start with Letter ? Ensures the password begins with an alphabetic character, which is required by some websites and apps. Prevent Repeated Characters ? Ensures every character in the password is unique — no character will appear more than once.

🔒 Security Tips

✅Use a unique password for every account — never reuse passwords.
✅Aim for at least 16 characters with mixed character types.
✅Store passwords in a trusted password manager (e.g. Bitwarden, 1Password).
✅Enable two-factor authentication (2FA) wherever possible.
✅Never share passwords via email, SMS, or chat.
✅All generation happens locally — no data ever leaves your browser.

❓ Frequently Asked Questions

Is this password generator secure? ▼

Yes. All passwords are generated entirely in your browser using the Web Crypto API — a cryptographically secure random number generator built into modern browsers. No password data is ever transmitted to a server, stored in a database, or logged in any way. The generation process never leaves your device.

Are passwords stored? ▼

No. Passwords are never stored on our servers or in any database. They exist only in your browser's memory for the duration of your session and are discarded when you close or navigate away from the page. We strongly recommend saving any password you want to keep in a trusted password manager such as Bitwarden or 1Password.

What length should a password be? ▼

Security experts recommend a minimum of 12 characters, with 16 or more being ideal for most accounts. For highly sensitive accounts — such as banking, email, or password managers — aim for 20+ characters. Longer passwords are exponentially harder to crack, even with simple character sets. Length is often more important than complexity alone.

What is the difference between a password and a passphrase? ▼

A password is typically a short, random string of characters (e.g. X7#kP2mQ). A passphrase is a sequence of multiple words strung together (e.g. Calm-Eagle-River-Storm). Passphrases are often longer, easier to remember, and just as secure — sometimes more so — because their length adds significant entropy. Use the "Memorable" or "Sentence" modes above to generate passphrases.

Should I use symbols? ▼

Generally, yes — adding symbols expands the character pool, which increases the number of possible combinations and makes brute-force attacks harder. However, some websites restrict which symbols are allowed. If a site rejects your password, try disabling symbols or using the "Exclude Ambiguous" option to remove characters that are commonly blocked. For most accounts, including symbols alongside uppercase, lowercase, and numbers gives you the strongest protection.
