Free Strong Password Generator
Generate cryptographically strong random passwords. Customize length, characters, and count. Free, in your browser.
Why this matters
Most people use the same 2-3 passwords everywhere, with small variations. That's a security disaster — one site gets breached, every account you have is at risk. The fix is unique passwords per site. The obstacle is remembering 50+ unique passwords. The answer: a password manager + strong generator.
This generator uses your browser's cryptographic random source. Choose a length and character types; every result includes each selected type. Passwords are generated locally and are not stored by this tool. Copy them into a password manager before leaving the page.
Best uses: creating unique passwords for accounts. This is a random-character generator, not a passphrase generator or an API-key provisioning service.

Frequently Asked Questions
Are these passwords stored anywhere?
No. Generation happens in your browser using crypto.getRandomValues. Nothing is sent to a server.
How strong are these?
Longer, unique random passwords are harder to guess. Every selected character type is included. The strength label is a rough heuristic, not a guarantee; use a password manager and multi-factor authentication where available.
Should I save these?
Use a password manager like Bitwarden, 1Password, or KeePass. Never email passwords or write them on paper.
Why is the strength meter sometimes wrong?
It's a heuristic, not a guarantee. Use the longest password your chosen service accepts.
