What is multi factor authentication, and how does it increase security?

Multi factor authentication is the use of several authentication factors together, which provides higher levels of security to verify it's you.

The True Key app always uses multi factor authentication, combining unique factors such as your Face, Fingerprint, or your Master Password with additional factors based on context such as your Trusted Devices.

For example, the True Key app will reject an attempt to log in with Face unless it comes from one of your own Trusted Devices. This protects you from an attacker who might try to spoof your face using a photo or video.
