What makes a password strong

Length and randomness, far more than swapping letters for symbols. A long random string is exponentially harder to crack. Aim for 16+ characters, use a unique password per account, and store them in a password manager. Prefer something memorable? Try the passphrase generator; want to check one? Use the strength tester.
