Two-factor authentication (2FA) adds a second layer of security to your accounts. Even if a criminal steals your password, they cannot access your account without the second factor (usually a code sent to your phone). Setting up 2FA is one of the most important security steps you can take.

- McAfee account: go to mcafee.com > My Account > Security > Enable Two-Step Verification
- App-based 2FA (Google Authenticator, Microsoft Authenticator) is more secure than SMS codes
- SMS 2FA is still much better than no 2FA at all
- McAfee True Key password manager supports biometric 2FA (fingerprint, face recognition)
