Password Generator

How the Password Generator Works

A strong password is long and random. This tool builds one from the character types you choose — uppercase, lowercase, numbers and symbols — picking each character at random in your browser, so the password is never sent anywhere. The more character types and the greater the length, the more combinations an attacker must try.

Strength is measured in bits of entropy: each added character multiplies the possibilities. Sixteen characters from a full set gives roughly 100 bits — far beyond brute-forcing. Use a unique password for every account and store them in a password manager.

combinations = character-set size ^ password length
