Why Multi-Factor Authentication Matters: A Guide I Wrote After Getting Hacked.

Summary
Multi-Factor Authentication (MFA) provides an additional layer of security when logging in, beyond just using a username and password.
There are three types of MFA: something you know (like a PIN or a secret question), something you have (such as a phone number, an email address, or an authentication app), or something you are (like a biometric fingerprint or facial ID).

The author urges readers not to wait to enable MFA until it’s too late.
