Staying Safe Online · Level 1 of 5 · Intro

Passwords and sign-ins

Strong unique passwords, password managers, and multi-factor authentication.

Study notes

Use a different password for every account. If one site is breached, the others stay safe.
Long passphrases (several random words) are easier to remember and harder to crack than short complex passwords.
A password manager creates and stores strong unique passwords so you only remember one main password.
Turn on multi-factor authentication (MFA). An authenticator app or security key is stronger than text-message codes.
Never share one-time codes. A real company will not call and ask you to read a sign-in code back to them.
