Frequently asked questions
How does this password generator work?
It uses the Web Crypto API — a cryptographically secure random number generator built into your browser. This produces genuinely unpredictable passwords. Nothing is sent to any server.
Are the generated passwords stored anywhere?
No. Passwords are generated entirely in your browser. Nothing is logged, stored, or transmitted. Close the tab and the password is gone forever.
How long should a strong password be?
16 characters is sufficient for most accounts. For high-value accounts like email, banking or password managers, use 24+ characters. The entropy display shows exactly how strong each password is.
Should I use a password manager?
Yes. Use this generator to create unique passwords for every account, then store them in Bitwarden (free), 1Password, or Dashlane. Never reuse passwords across accounts.
What does entropy mean?
Entropy measures how unpredictable a password is in bits. 80+ bits is strong. 128+ bits is very strong. A password with 128 bits of entropy would take longer to crack than the age of the universe.
