How do I install an authenticator app to use for multi-factor authentication (MFA)?

Since both your CUNY Login and Microsoft 365 accounts use multi-factor authentication for increased security, an authenticator app on your mobile device is required. Authenticator apps generate time-based, single-use, codes that are used for account verification.

• Microsoft Authenticator (recommended by CUNY)
• Google Authenticator
