2025 Cybersecurity Awareness Month: Turn on Multifactor Authentication

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.
