Password Generator
Generate strong, secure passwords with customizable length and character sets. Uses Web Crypto API for cryptographic randomness.
About Password Security
A strong password is your first line of defense against unauthorized access to your accounts and data. Strong passwords should be at least 12 characters long and include a mix of uppercase letters, lowercase letters, numbers, and symbols to maximize entropy.
Adjust the password length slider, toggle character types on or off, and click Generate to create a cryptographically secure random password. The strength meter provides instant feedback based on length and character diversity. Enable 'Exclude ambiguous characters' to avoid easily confused characters like 0/O and l/1/I.
Password generation is needed for creating unique passwords for every online account, generating secure API keys and tokens, setting up database credentials, creating Wi-Fi passwords, and establishing master passwords for password managers. Never reuse passwords across different services.
This tool uses the Web Crypto API (crypto.getRandomValues) for true cryptographic randomness — the same entropy source used for TLS encryption. A 16-character password with all character types has approximately 96^16 possible combinations, which would take billions of years to brute-force with current hardware. All generation happens in your browser with no passwords stored or transmitted.
