What is Password Generator?
Generate strong, secure passwords.
How the password generator works
Every character is chosen with crypto.getRandomValues — the browser's cryptographically secure random source — using rejection sampling so that no character is more likely than another. That subtle uniformity is exactly what Math.random-based generators get wrong. The password is created and stays in your browser; nothing is transmitted. Following NIST SP 800-63B, length is the dominant factor in resistance to guessing, so favour 16 characters or more over forced composition rules — a longer all-lowercase passphrase beats a short string padded with mandatory symbols.
