What makes a password strong?
Length and unpredictability matter most. A long password made of truly random characters is far harder to guess or brute-force than a short one built from words and patterns.

Frequently asked questions
Is this password generator safe?
Yes. Passwords are generated locally with the Web Crypto API. Nothing is uploaded, logged or stored.
How long should a password be?
At least 14 characters for normal accounts, and 20 or more for important ones such as email or your password manager.
Why exclude look-alike characters?
Characters like I, l, 1, O and 0 are easy to confuse when you have to type a password by hand.
