Cybersecurity Tip of the Week – Cybersecurity Basics – Step 2 – Enable Multifactor Authentication (MFA)

According to the National Cybersecurity Alliance, there are four cybersecurity basics everyone should use for online safety. Part two of our four-part series is about multifactor authentication (MFA).

Multifactor authentication (sometimes called 2FA) adds an extra security layer by requiring something more than just your password to log in. Think of it as using two locks on your digital door instead of only one. This could be:

  • A one-time code sent to your phone or email

  • A biometric scan, like a fingerprint scan or FaceID

  • A physical security key

Enable MFA on your accounts, especially email, banking, and social media. It's a simple way to supercharge the security on your accounts. Also, never share MFA codes with anyone; this includes not sharing them over the phone, through texts, or via email. Only scammers will ask for MFA codes.
