What makes a password strong?

Length and randomness are key. Use 12–16+ characters and a mix of character sets. The tool shows an entropy estimate to help you gauge strength.

Are the generated passwords stored or uploaded?

No. Passwords are generated locally in your browser. Nothing is sent to a server unless you explicitly export to a file on your device.

What is a passphrase and when should I use it?

A passphrase is a sequence of random words (e.g., Diceware). It can be easier to remember while still offering high entropy if you include enough words.

Can I enforce custom password policies?

Yes. You can require certain character classes and even use custom regex checks to ensure generated passwords meet your policy.
