What is MFA and where should you use it?
Multifactor authentication (MFA) provides an extra layer of security for your accounts by requiring a quick second step to verify your identity when logging in.
Use it on every account that offers it, especially:
- Email
- Accounts with financial information
Ex: Banks, online stores - Accounts with personal information
Ex: Social media
Which MFA methods are best?
Choose the most secure MFA method available. Here are some options, from most to least secure:
- Security key: Use a physical security key (such as a YubiKey) to log in. It plugs in or taps your device. It provides the best protection against phishing and is easy to use.
- Authenticator app with number matching: An app prompts you to enter a number on your phone. You enter a number shown on the login screen to confirm your identity.
- Authenticator app with one-time code: An app generates a new code every 30 seconds.
- Biometrics: Uses your fingerprint or face to confirm your identity.
- Text or email code: A one-time code is sent to your phone or email. Least secure method.
