A new employee at a company is trying to access a secure system. Before gaining entry, they must provide their account name and a unique code sent to their mobile device. What is this process called?
Single factor authentication
Permission granting
Username verification
Multifactor authentication
This process is known as multifactor authentication (MFA), which requires a user to provide two or more different types of verification to prove their identity. In this scenario, the user combines a password associated with their account name (something they know) with a unique code sent to their mobile device (something they have). Using multiple factors significantly increases security compared to using only a single factor like a password.
