FAQ
How much entropy is strong?
Around 75+ bits is considered strong against offline attacks. Length beats complexity: a 16-character mixed password usually outperforms a shorter one with symbol substitutions.
Does adding symbols really help?
Less than adding length. Each symbol grows the pool to 95 characters, but every extra character multiplies guesses — a 16-char passphrase beats a short symbol-soup password.
Why does reuse weaken a password?
Breaches leak passwords in bulk. If the same password is used elsewhere, attackers replay it automatically — unique passwords per site are essential.
