Manage Your Multi-Factor Authentication (MFA) Methods

Review, add, update, and manage the multi-factor authentication (MFA) methods associated with your OHIO account. This article explains how to view your current authentication methods, add new methods, change your default sign-in method, remove outdated devices or phone numbers, and ensure your account is ready for Microsoft's upcoming MFA changes.

Overview

Microsoft is retiring SMS text message and phone-call authentication methods beginning February 1, 2027. If you currently use these methods to verify your identity when signing in to your OHIO account, you should add and use another authentication method before that date.

This article will show you how to:

• Review your current authentication methods
• Add a new authentication method
• Change your default authentication method
• Remove outdated devices or phone numbers
• Make sure your account is ready for upcoming Microsoft MFA changes

This information is also available in our video tutorial.

Recommended Authentication Methods

Ohio University recommends the following authentication methods:

• Microsoft Authenticator App - preferred
• Passkeys
• Hardware Security Token (where applicable)

It is also recommended that you register at least two authentication methods whenever possible. This can help you regain access to your account if you lose or replace a device.

• Phone (support ending Feb. 2027)
• Text message (support ending Feb. 2027)

Take a moment to verify that:

• Your information is current
• Your devices are still available to you
• You recognize all listed authentication methods
• You have enabled the Microsoft Authenticator app as your preferred authentication method
