Understanding Password Entropy
Entropy measures the unpredictability of a password. Higher entropy means more possible combinations and longer crack times. A 12-character random password with mixed case, numbers, and symbols has ~78 bits of entropy. A 4-word passphrase like "correct horse battery staple" achieves strong security through length rather than complexity.
Best practices: use a password manager, enable 2FA, avoid dictionary words and predictable patterns, and prefer long passphrases over short complex passwords.
