Zero Storage • Military-Grade Randomness • Never Tracked

No passwords generated yet
Our generator uses cryptographically secure random number generation (crypto.getRandomValues) which provides military-grade randomness. All passwords are generated entirely in your browser using JavaScript - nothing is ever sent to our servers or stored anywhere. Each password is truly random and unpredictable.
Both are secure when properly generated. Passwords like "K9$mP2@xL5#nQ8" are very secure but hard to remember. Passphrases like "Correct-Horse-Battery-Staple" are easier to remember and type while still being extremely secure. A 4-word passphrase has about the same entropy as a 12-character random password.
The time shown assumes an attacker making 10 billion guesses per second (high-end GPU cluster). A 16-character password with mixed characters would take centuries to millennia to crack. However, if your password is found in a data breach or is a common pattern, it could be cracked instantly - always use unique passwords!
If one service gets hacked and your password is exposed, attackers will try that same password on other services (credential stuffing). Using unique passwords ensures one breach doesn't compromise all your accounts. Use a password manager to remember them all.
Length is the most important factor - every additional character exponentially increases security. A mix of character types (uppercase, lowercase, numbers, symbols) also helps. Avoid dictionary words, personal information, keyboard patterns (qwerty), and common substitutions (p@ssw0rd).
