Password strength checker
See how strong a password is as you type. It's scored live in your browser and never sent anywhere.
Test a password
Type a password to see how strong it is, scored live in your browser. Nothing is sent anywhere. Strength here is about structure; a strong password can still be leaked, so check it against the breach checker too.
- 12+ characters (longer is stronger)
- Mix upper case, lower case, numbers, and symbols
- Never reuse it on another account, that's how one breach becomes many
Scored entirely on your device. Nothing you type is sent or stored anywhere.
Rekey generates strong, unique passwords and walks you through changing the breached ones. Join the early-access list.
