How Password Strength Is Measured

Password strength is measured in entropy bits. Entropy quantifies how unpredictable a password is, based on the size of the character pool and the password length. Higher entropy means more possible combinations, making brute-force attacks exponentially harder.

Formula

Entropy bits = length × log₂(pool size)

Pool Size Sum of characters from each enabled type

Real-Life Examples

WiFi

WiFi Password: Use 16+ characters with mixed types. WPA3 with a strong password is nearly unbreakable.

Banking

Online Banking: Use 16-20 characters with symbols. Enable two-factor authentication for extra security.

Admin

Admin / Root: Use 20+ characters. Never reuse across systems. Consider a password manager.

API Key

API Keys: Use 32+ characters with full random pool. Rotate periodically and store securely.

Disclaimer: Generated passwords use cryptographically secure randomness via the Web Crypto API. For maximum security, always use a reputable password manager and enable two-factor authentication where available.
