About this tool

Strong passwords are your first line of defense against unauthorized access. Our Password Generator creates cryptographically secure passwords using the Web Crypto API, ensuring true randomness that cannot be predicted or reproduced. Choose from 5 presets (PIN, Simple, Strong, Maximum, Passphrase-like) or customize every aspect: length from 4 to 128 characters, character sets (uppercase, lowercase, numbers, symbols), exclusion of ambiguous characters (0, O, l, 1, |), and custom character exclusions. Generate up to 20 passwords at once, each with an individual entropy score and strength rating. The tool calculates password entropy in bits — a measure of how many guesses an attacker would need. A password with 80+ bits of entropy is considered strong against modern brute-force attacks. All generation happens in your browser using window.crypto — no passwords are ever transmitted or stored.
