Password Generator

Generate cryptographically secure random passwords with customizable length and character sets.

Configuration

Password Length: 16

Character Sets

Uppercase (A-Z) Lowercase (a-z) Numbers (0-9) Symbols (!@#$%...)

Number of Passwords: 1

1 10

Entropy: Measure of password randomness. Higher entropy = more secure. 60+ bits is acceptable, 80+ is strong, 100+ is very strong.

Length Matters: Longer passwords are exponentially more secure. A 16-character password is vastly stronger than 8 characters.

Character Diversity: Using all character types (uppercase, lowercase, numbers, symbols) increases the character pool and entropy.

Cryptographic Randomness: This tool uses crypto.getRandomValues() for true random generation, not predictable pseudo-random algorithms.

Best Practices: Use unique passwords for each account. Consider a password manager to store generated passwords securely.
