Multi-Factor Authentication (MFA) is a security mechanism designed to enhance the protection of user accounts by requiring multiple forms of verification before granting access. One of the critical triggers for MFA is unusual login attempts from suspicious locations.

When a login attempt is made from a location that deviates from the user's regular access patterns, it raises a red flag for potential unauthorized access. In such instances, MFA is invoked to ensure that the person attempting to log in is indeed the legitimate user. This might involve sending a code to the user's phone or requiring them to verify their identity through another method, such as answering security questions or utilizing biometric data.

The other choices do not accurately reflect scenarios that would trigger MFA. For example, regular login attempts from verified devices do not pose a threat; hence, they would not necessitate additional authentication layers. Logins during work hours typically do not raise concerns about suspicious access unless combined with other risk factors, and password changes made by the user generally affirm identity rather than triggering MFA.
