What is Password Generator?

Generates cryptographically random credentials with high information entropy to protect online accounts against brute-force and dictionary attacks.

How to Use This Calculator

  1. Select desired character length (16+ recommended).
  2. Toggle uppercase, numbers, and symbols.
  3. Copy your unique generated password.

The Mathematical Formula & Variables

Entropy Bits = Length * log2(Character Pool Size)

Step-by-Step Worked Example

Scenario: 16-character password using 94 printable ASCII characters (pool size N = 94).

  1. log2(94) = 6.55 bits per character.
  2. Entropy = 16 * 6.55 = 104.8 bits (virtually unbreakable).

Result: 104.8 Bits Entropy
