Common use cases

How it compares

Password managers (1Password, Bitwarden, LastPass) include built-in generators but require the app. Random-password-generator.com and similar have ads. Freepasswordgenerator is the clean ad-free no-install option.

Privacy

Passwords are generated in your browser using the Web Crypto API. The generated password appears only on your screen and is never transmitted or logged.

Frequently asked questions

Is Freepasswordgenerator free?

Yes. Ad-free, no signup.

Are the passwords truly random?

Yes. Uses crypto.getRandomValues() which the browser backs with a cryptographically secure random number generator.

Are passwords sent anywhere?

No. Everything is client-side. The password is generated in your browser and displayed only to you.

What length should I pick?

12-16 characters with mixed case, digits, and symbols is sufficient for most uses. 20+ for critical accounts.

Should I use this instead of a password manager?

Password managers store and autofill passwords across devices. Freepasswordgenerator is for one-off generation. Use both together: generate here, store in your manager.

What are "ambiguous characters"?

Characters that look alike in some fonts: 0 (zero) vs O (letter), l (lowercase L) vs 1 (one), I vs l. Excluding them makes passwords easier to type from a printed copy.
