What is Multi-Factor Authentication (MFA)?

Multi-Factor Authentication (MFA)

Definition

A security process that requires users to provide two or more verification factors to access a resource, such as a website, application, or online account.

This enhances security by adding layers of authentication, making it harder for unauthorized users to access sensitive information.

Work Email: Accessing email from outside the office requires a password and confirmation via an authenticator app.
