It estimates entropy in bits — each extra bit doubles the guessing effort.
Do you store the passwords I generate?
Never. Nothing is logged or transmitted; close the tab and it's gone.
What makes a strong password?
A strong password is long (12+ characters), uses a mix of uppercase, lowercase, numbers and symbols, and doesn't contain real words or personal information. A passphrase of 4+ random words is also very strong and easier to remember.
What is the difference between a password and a passphrase?
A passphrase is a sequence of random words (like 'amber-rocket-village-7') that is long enough to be secure but easier to remember than a random character string.
Is it safe to generate passwords in a browser?
Yes. This tool uses the browser's built-in cryptographic random number generator (Web Crypto API) and never transmits anything — close the tab and the passwords are gone.
How often should I change my passwords?
Current guidance (NIST) says you don't need to change passwords on a schedule — only change them if you suspect a breach. Using a unique strong password for every site matters more than frequent changes.
