About this password generator
This free password generator creates strong, random passwords entirely in your browser using the cryptographically secure crypto.getRandomValues API — the same source of randomness recommended for security-sensitive use. You control the length and which character sets to include, and the strength meter estimates the entropy in bits so you can see how hard the password is to guess. No password is ever uploaded, logged or stored.
Frequently asked questions
- Are these passwords safe to use?
- Yes — they are generated locally with a cryptographically secure random source and never leave your device.
- How long should my password be?
- 16+ characters with mixed character sets is strong for most accounts. Aim for 80 bits of entropy or more for important logins.
- What does "exclude ambiguous" do?
- It removes look-alike characters (I, l, 1, O, 0, o) so the password is easier to read and type by hand.
