analyzed locally · never sent anywhere*Worst-case: 10 billion guesses/second (a multi-GPU rig against a fast hash). A slow hash like bcrypt/Argon2 takes far longer.
How to create a strong password
Choose Random for a classic password — pick a length (16+ recommended), select which character types to include, and optionally exclude look-alike characters. Or switch to Passphrase for a memorable string of random words you can actually remember. The strength meter shows the estimated entropy in bits so you can see how hard it is to crack. Everything is created locally and never leaves your device.
