Frequently asked questions
Are these passwords safe to use?
Yes. Passwords are generated in your browser using the cryptographically secure Web Crypto API, and nothing is sent over the network.
What is entropy and how much do I need?
Entropy estimates how hard a password is to guess, in bits. 70+ bits is strong for most accounts; aim for 100+ for high-value or long-lived secrets.
Why exclude similar characters?
Characters like l, I, 1, O and 0 are easy to misread. Excluding them helps when a password must be typed or read aloud.
