Q: Why is MFA needed?
A: MFA prevents unauthorized access to your data and applications by requiring a second method of verifying your identity, making your account much more secure.
Q: How often will this need to be done?
A: The above steps only need to be completed once to enable MFA.
Q: How long will my account be authenticated?
A: The authentication should last until you log off of the PC.
Q: What if I cannot install an authentication app on my mobile device?
A: You may choose to use phone/text as your authentication method, or alternatively, you can purchase a YubiKey and follow the setup instructions in the associated article. Please note that Microsoft will soon no longer support phone/text as an authentication method for MFA.
