How can MFA enhance security for Azure Virtual Desktop logins?

Multi-Factor Authentication (MFA) significantly enhances security by requiring users to provide multiple forms of verification before granting access to Azure Virtual Desktop. This process typically involves something the user knows (like a password) and something the user has (like a smartphone or hardware token) or something the user is (such as a fingerprint). This layered approach makes it much more difficult for unauthorized users to gain access, as they would need to compromise multiple forms of authentication rather than just a single password.

In scenarios where passwords may be weak or vulnerable to phishing attacks, the additional verification steps required by MFA serve as a formidable security barrier. This is particularly important in a cloud environment where sensitive data is often accessed remotely, enhancing overall data protection and compliance with security policies.

Other options, while they may contribute to security in various ways, do not directly relate to the core concept of MFA. For instance, logging users out after inactivity can help mitigate risks associated with unattended sessions, but it does not ensure that the right person is logging in. Encrypting user data during transmission protects data integrity and confidentiality but does not authenticate users. Limiting access to specific IP addresses can restrict who can attempt to log in, but it does not enhance authentication once a login is attempted. Therefore
