Multifactor Authentication (MFA) is available by request at this time. Before you can enroll, please submit a request to enable MFA for your account.

After MFA has been enabled for your account, the next time you log into Office 365 you will be prompted to provide more information. Click Next to begin enrolling. It is recommended that you enroll using a desktop or laptop computer. 



The Microsoft Authenticator app is the recommended tool for multifactor authentication with your Office 365 account. This app provides push notifications or time-based one-time passwords (TOTP) to allow approval for sign-ins. You can also add other accounts that use TOTP. Alternatively, you can use other authenticator apps that support TOTP, but you won't receive push notifications to authorize your logins and we can't support other apps. For instructions on setting up MFA with the Microsoft Authenticator app, see this solution article: Enrolling in Multifactor Authentication for Office 365 with the Microsoft Authenticator App


Alternatively, you can receive a text message with a passcode to authenticate your login. 


To set up text messages, click the "I want to set up a different method" button at the bottom of the enrollment screen.



In the pop-up box, click the dropdown and choose Phone, then click Confirm.




On the next screen, type in the phone number where the text messages should be sent and click Next.


You will receive a text message from Office 365 that contains a passcode. Type that passcode into the next screen to verify MFA has been configured then click Next.




To complete the enrollment process, click Done on the Success page.



Any time you log into Office 365, you will now receive a text message to your mobile device to verify your login. If you receive a text message when you are not trying to log in, you should change your password immediately. You can bypass these text messages for 30 days on trusted devices. 



If you are using Outlook, or have your email account set up on a mobile device, you should be prompted to reauthenticate using MFA. Most modern email clients will take you to the Arkansas Tech Single Sign-On (SSO) page and walk you through the MFA approval process. If your mobile device does not send you to SSO, you may need to remove the account from your device and set it up again. 

Legacy applications may not support the modern authentication process used for MFA. If you are using an app that will not send you to SSO, you may need to use an app password.
