About Password Security
Understanding Password Strength
Password strength is determined by several factors including length, character variety, and unpredictability. A strong password should be long enough to resist brute-force attacks and complex enough to resist dictionary attacks.
Password Entropy
What is Password Entropy?
Entropy measures the unpredictability of a password. Higher entropy means a more secure password. It's calculated based on the length of the password and the size of the character set used.
Entropy = Length × log₂(Character Set Size)
