Strength: Strong · 129 bits of entropy

How it works

Generate strong, random passwords in your browser using a cryptographically-secure random number generator. Choose the length and which character sets to include, optionally excluding look-alike characters, and see the estimated entropy. Nothing is uploaded.

Frequently asked questions

Are these passwords safe to use?

Yes — each character is chosen with your browser’s crypto-secure random generator (unbiased), entirely on your device. No password is ever sent anywhere.

How long should my password be?

Aim for at least ~80 bits of entropy. With a full character set that is roughly 14+ characters; the strength meter shows the estimate.

What does “no look-alikes” do?

It removes easily-confused characters like 0/O and 1/l/I so the password is easier to read and type without weakening it much.
