FAQ
Is this password generator safe?
Yes. Passwords are created in your browser with the Web Crypto API and are never sent or stored.
How long should a password be?
At least 14–16 characters for important accounts. Longer is stronger; aim for 80+ bits of entropy.
What is password entropy?
A measure of how hard a password is to guess: length × log2(size of character set). More bits = stronger.
Should I reuse passwords?
No. Use a unique password for each account and store them in a password manager, plus two-factor authentication.
