Common questions
Quick answers about these free tools.
Is it safe to generate passwords in a browser?
Yes, when it's done locally. These tools use crypto.getRandomValues and never send the password over the network. Store passwords in a password manager.
Do you log what I type into the strength checker?
No. The check runs entirely on your device.
