Brute-Force Attack

A brute-force attack tries to crack a password or key by systematic trial and error: a program automatically tests huge numbers of combinations per second until it finds the right one. Short or common passwords fall in seconds this way, while long, random ones practically never do. You're protected by long, unique passwords (ideally from a password manager), two-factor authentication, and lockouts after several failed attempts.
