Enabling Multi-Factor Authentication (MFA) requires users to provide additional information beyond just a password. MFA is a security process that requires more than one form of verification to grant access to a system, application, or account. Typically, this involves something the user knows (like a password) and something the user has (like a smartphone app that generates time-based one-time passwords, or a hardware token).

This approach enhances security significantly because even if a password is compromised, unauthorized access is still thwarted by the requirement for that additional factor. This multi-layered security measure can involve different types of authentication, such as entering a code sent via SMS, using an authentication app, or providing biometric data like fingerprints.

In contrast, relying solely on a password or other single factors does not provide the same level of security as employing MFA, making it a crucial practice for protecting sensitive information against potential breaches.
