How Password Generation Works

Set Length: Choose password length (8-128 characters).

Select Characters: Include uppercase, lowercase, numbers, symbols.

Set Options: Exclude ambiguous characters, require diversity.

Generate: Create cryptographically secure random password.

Password Strength Formula

Entropy = log₂(Character Set^Length)

Character Set: 26 lowercase, 26 uppercase, 10 numbers, 32 symbols

Strong Password: 12+ characters with mixed types

Entropy Score: 60+ bits for strong security

Random Source: Cryptographically secure RNG

Example Password Generation

A 16-character password with all character types: "Kj9#mP2$xL5@nQ8!" has 95 bits of entropy, making it virtually impossible to crack through brute force. This would take trillions of years to crack with current computing power. A simple 8-character password with only lowercase letters: "password" has only 37 bits of entropy and can be cracked in minutes.

This demonstrates why password complexity and length matter.
