Jinsi ya kukokotoa Password Strength

Password Strength ni nini?

A password entropy calculator measures the cryptographic strength of a password in bits: entropy = log₂(character set size^password length). A 12-character password using upper, lower, digits, and symbols has ~79 bits of entropy. At least 60–70 bits is generally recommended; password managers make using high-entropy passwords practical.
