Password generator

Strength: excellent (99 bits of entropy)

Passwords are generated in your browser with a cryptographic random generator (crypto.getRandomValues) and are never sent or stored anywhere.

This password generator creates strong, random passwords and rates them with a live strength meter based on entropy. Pick the length and which character types to include.

Strong passwords, generated locally

Toggle uppercase, lowercase, numbers and symbols, or exclude ambiguous characters for passwords you’ll type by hand. Everything runs in your browser with a cryptographic random generator — nothing is sent or saved.

FAQ

Are these passwords safe to use?

Yes. They're created with your browser's cryptographic random generator (crypto.getRandomValues) and never leave your device or get stored anywhere.

How long should my password be?

Aim for at least 16 characters with a mix of types. The strength meter shows entropy in bits — 80+ bits is excellent for important accounts.

What does 'exclude ambiguous' do?

It drops easily confused characters like l, 1, O and 0, which is handy when a password has to be read or typed by hand.
