What makes a password strong?
Password strength depends on length and character variety. A 16-character password using all four character sets has over 10²⁹ possible combinations, making brute-force attacks computationally infeasible. Longer passwords (20+) provide extra security margin even with fewer character sets. Never reuse passwords across services — use a password manager to store them.
