Multi-factor authentication (MFA) is a method of authentication that requires the use of more than one verification method and adds a second layer of security to user sign-ins and transactions. It works by requiring any two or more of the following verification methods:
- A randomly generated pass code
- A phone call
- A smart card (virtual or physical)
- A biometric device
