Setting up Multi-factor Authentication for Microsoft 365

For security purposes, multi-factor authentication is required for all employees. After you've received your credentials from your manager or IT, you configure your multi-factor authentication by logging into your Microsoft 365 account for the first time. The following steps will guide you through this process.

Open a web browser and go to https://myaccount.microsoft.com/

The default authentication method is to use the free Microsoft Authenticator app. To use this authentication method, you must install the app on your mobile device by downloading it from the Apple App Store (for iPhones) or Google Play Store (for Androids). Once installed on your mobile device, follow the prompts to add your work account to the app.
If you would rather use SMS messages sent to your phone instead, select "I want to set up a different method". Microsoft 365 will ask for your mobile number, then send you an SMS message containing a 6-digit code to verify your device.
Each time you sign into a new device, you will be required to approve your login using your multi-factor authentication method. Known devices will require multi-factor authentication every 30 days.
