MFA

What is it?

Multi-Factor Authentication (MFA) is a security method that requires more than just a password to log in—usually something you know (password) and something you have (like a code on your phone).

Why it matters

MFA dramatically reduces the risk of unauthorized access, even if a password is stolen.

Simple example

After entering your password, you receive a text or app notification asking you to confirm it’s really you.
