What is Multi-Factor Authentication

In multi-factor authentication, we expand on the traditional requirements that exist in a single factor authentication.To accomplish this, multi-factor authentication will use another factor for authentication in addition to the traditional password authentication.

Multi-factor authentication is more secure single factor authentication, because it adds steps that increase the layers of security.
