Multifactor Authentication (MFA)

What is MFA?
This authentication method supplements passwords to provide an online account with a second layer of security; it does not replace passwords.

How does MFA work?
There are a variety of MFA methods available, all of which have the same end goal: providing a way of proving a login is legitimate that's separate from the password.

Why does MFA matter?
Most everything we do on a computer or mobile device is exposed to the internet, and that means those online accounts can be compromised. Adding MFA to an account makes it harder for a stolen password to be used against you.

How safe is MFA?
Nothing is completely secure, and that includes MFA. MFA systems have been hacked in the past, but the biggest risk isn't technological--it's social engineering, which can bypass even the most secure of systems.”
