Generate strong, secure random passwords instantly. Customize length and character types. Uses cryptographic randomness for maximum security.
This tool uses the Web Crypto API (crypto.getRandomValues) to generate cryptographically secure random passwords. You can customize the length and choose which character types to include: uppercase, lowercase, numbers, and symbols.
A strong password is at least 12-16 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and symbols. The strength is measured in bits of entropy — higher entropy means harder to crack.
Yes. Passwords are generated entirely in your browser using cryptographic randomness. No passwords are sent to any server or stored anywhere.
For most accounts, 16 characters with mixed character types is considered very strong. For high-security needs, use 20+ characters. The entropy indicator on this tool helps you gauge the strength.
