What makes a password strong?

A strong password is at least 12 characters long, includes uppercase and lowercase letters, numbers, and special characters, and avoids common words or patterns.

How is password strength calculated?

We analyze length, character variety, common patterns, keyboard sequences, repeated characters, and dictionary words to calculate strength.

Entropy measures the randomness of a password in bits. Higher entropy means more possible combinations, making it harder to guess or crack.
