Frequently asked questions
Is this password generator free?
Yes. You can generate unlimited passwords for free, with no sign-up required.
How random are these passwords?
Passwords are generated using the Web Crypto API (crypto.getRandomValues), the same cryptographically secure randomness browsers use for security-sensitive operations — not Math.random(), which is not safe for passwords.
Do you store or see my generated passwords?
No. Password generation happens entirely in your browser. We never receive, log or store what you generate.
What does the strength meter mean?
It estimates the password’s entropy from its length and character variety. Longer passwords with more character types score higher.
Should I exclude similar characters?
Only if you need to type or read the password manually. For passwords you copy and paste, leaving this off gives you a slightly larger, stronger character pool.
