What is multi-factor authentication?
Multi-factor authentication creates several layers of additional security to reinforce your password access to a website, app or piece of software.
Authentication can include a physical key that generates unique passwords, it might be an app on your phone, like the Google Authenticator, or it could be biometric data like your fingerprint or retinal scan.
