Recent passwords (cleared when you leave this tab)
Build a truly random password, or paste one in to see exactly how strong it is — length, character mix, patterns and an estimated crack time. Everything runs on your device, nothing is ever sent anywhere.
Everything runs locally, so nothing about your passwords ever touches a server.
Pick a length and which character types to include.
Click Generate password to create a new random password.
One click copies the password to your clipboard.
Switch tabs and paste any password you already use.

Save the password in a trusted password manager.
Uses your browser's cryptographic random number generator, not predictable math.
Watch the strength score update as you adjust length and character options.
Passwords are generated and analyzed on-device and never uploaded anywhere.
