Microsoft, the university’s multifactor authentication (MFA) provider, is making major changes to available MFA options to strengthen authentication security. Beginning February 1, 2027 text message and phone call verification will no longer function as MFA methods. If you currently use text message or phone calls as your MFA verification method, you must change to a supported method to continue using university technology services.

Microsoft continues to support multiple MFA verification options, including the preferred and most secure option: Passkey in the Microsoft Authenticator app. If you are relying on text message or phone call MFA verification methods, you should download the Microsoft Authenticator app and set it up as soon as possible.

Frequently Asked Questions

What’s changing?  

On February 1, 2027, Microsoft will retire native text and call verification as MFA verification methods. After this date, a different method like Passkey in the Microsoft Authenticator app will be required to log in to university systems.   

Beginning soon, anyone who uses text messages or phone calls for sign-in authentication to Missouri State systems will be prompted to set up a more secure verification method.  

Why is this happening?

Phone calls and text messages are increasingly targeted by cyberattacks (such as SIM swapping and phishing). Microsoft is encouraging all users to adopt passkeys, which are highly resistant to phishing and theft providing stronger protection for campus and personal data.    

Why use Passkey in the Microsoft Authenticator App?

Passkeys are the most secure MFA verification option and are are highly resistant to phishing and theft. Passkey in the Microsoft Authenticator app is the best option for most people because it provides the strong security of Passkeys while maintaining the convenience and portability of the Microsoft Authenticator App, which most users are already familiar with.

What does this mean for you?

• If you already use a passkey or other phishing-resistant authentication method, you may not notice a change. 

• If you use text messages or phone calls for verification, you will start being prompted to set up a passkey after signing in. 

• You may be able to postpone setup at first, but completing it early will help prevent sign-in problems later. 

• Instructions for setting up MFA and passkeys can be found at How to Set Up Your Account Security Information.
