Password Generator
Make strong random passwords of any length.
Questions
How random are these passwords?
They come from crypto.getRandomValues, the cryptographically secure generator built into your browser, and every character is picked with equal probability. The strength shown is the password’s entropy: 20 characters from all four sets give about 130 bits, far beyond any guessing attack.
Are the passwords saved or sent anywhere?
No. They exist only in this page until you close or refresh it. Passwords are never stored in your browser or sent anywhere.
How long should a password be?
For accounts that matter, 16 characters or more, different for every site. A password manager can store them, so you never need to remember or reuse one.
What does “Avoid look-alike characters” do?
It leaves out I, l, 1, O, 0 and o, which are easy to confuse when a password is read aloud or typed from paper. The password is slightly less random per character, so the tool shows the adjusted strength.
Is it free? Do I need an account?
It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
