Multi-factor authentication (MFA) is an important extra layer of security for your M365 account. With MFA, you must provide another piece of information after signing in with your username and password. This second factor is commonly a random code sent to your phone as a text, voice call, or generated in a dedicated authenticator app.
MFA is required for all CUNY M365 accounts and for all M365 applications (including Outlook, Teams, Office 365 web applications, OneDrive, and M365 mobile apps).
Learn about the different M365 MFA options.
Setting up Multi-Factor Authentication
- When you first sign in to your Microsoft 365 account you will be prompted by a message that says “More information is required.”
- Follow the steps to use Microsoft Authenticator (recommended) or click the link to use a different authenticator app. If you don’t want to use an authenticator app, click “I want to setup a diff method” at the bottom to verify using a voice phone number or text message.

How do I add another MFA verification option?
After enabling your first MFA verification option, open your M365 account security info page to add other options (including your office phone number and Google Authenticator) or change/remove options.
IMPORTANT: If you enable other voice/text verification options and require access to your college email when traveling outside of the country, ensure that you have access to the phone number used for MFA verification or enable one of authenticator app options, like Microsoft Authenticator.
