Microsoft Two-Factor Authentication Enforcement Notice

Effective January 15th, 2024, Microsoft will enforce two-factor authentication (2FA) for all Office 365, Email, and SharePoint access. This security mandate may also affect the scan-to-email function of your copier.

Two-factor authentication (2FA) is a specific type of multi-factor authentication (MFA) that strengthens access security by requiring two methods (also referred to as authentication factors) to verify your identity.

2FA is an extra layer of security used to ensure that people trying to gain access to an online account are who they say they are. First, a user will enter their username and a password. Then, instead of immediately gaining access, they will be required to provide another piece of unique information.

The next time a user signs into a device, they will be prompted to authenticate using their preferred 2FA method. There are three options to complete the 2FA setup. 

Option 1: SMS Verification

  • Users receive a one-time code via SMS to their registered mobile number.
  • That code is entered during the setup process for verification.

Option 2: Authenticator App

  • Users install an authenticator app (e.g., Google Authenticator, Authy) on their mobile device.
  • The app generates a time-based one-time code for 2FA.
  • Users scan a QR code or manually enter a setup key during the registration.
  • Users need to have a compatible device and install an app.

Option 3: Email Verification

  • Users receive a unique code or link via email.
  • They click the link or enter the code during the setup for verification.
