About the Password Generator
A strong password is long and random, which makes it hard to guess or brute force. This generator builds one for you using your browser's secure random number generator.
You control the length and which character sets to include (lowercase, uppercase, numbers and symbols), and can exclude ambiguous characters like O and 0 for passwords you need to type by hand.
The strength meter estimates entropy in bits, so you can see how resistant your password is. Nothing you generate is stored or sent anywhere.
