What is it

A strong password uses sufficient length and varied character types to resist guessing and brute force. This tool uses the browser cryptographic RNG (crypto.getRandomValues), supports ambiguous-character exclusions, custom excluded characters, multiple outputs, and passphrase mode, and never sends anything to a server.

random password = crypto random index mapped to selected character pool

How to use

FAQ

Is the generated password sent to a server?

No. All generation happens in the browser and nothing is sent to a server.

What length is recommended?

At least 12 characters, ideally 16+, mixing several character types.

Where should I store generated passwords?

Use a password manager and keep a unique password per site. Never reuse the same password across services.

Are passphrases more secure?

At equal length, random-character passwords are stronger, but a long passphrase of four or more words is easier to remember while still providing solid strength.
