🔐 Setting up Microsoft MFA for the First Time

1. Sign in to your Microsoft 365 account

   • Go to https://portal.office.com

   • Enter your new Microsoft email address (e.g., yourname@yourdomain.com) and temporary or assigned password.

   • You’ll be prompted to set up additional security (this is MFA).

2. Download the Microsoft Authenticator app

   • 

   • On your mobile phone, open the App Store (iPhone) or Google Play Store (Android).

   • Search for Microsoft Authenticator and install it.

   • Do not sign in inside the app yet—just leave it open.

3. Set up the Authenticator connection

   • On your computer, you’ll see the message “More information required” → click Next.

   • Choose Mobile app if prompted, then select Receive notifications for verification → click Next.

   • You’ll see a QR code on your screen.

4. Scan the QR code

   • Open the Microsoft Authenticator app on your phone.

   • Tap the + (Add Account) → choose Work or school account.

   • Point your phone’s camera at the QR code on your computer screen.

   • The account will appear in your app.

5. Approve the test notification

   • Microsoft will send a test prompt to your phone.

   • Tap Approve when it appears in the Authenticator app.

6. Finish setup

   • Once approved, you’ll see “Success!” on the computer.

   • Click Next → enter a backup phone number (optional but recommended).

   • Click Done to complete setup.

🧠 Tips

• Each time you sign in on a new device or browser, you’ll get a prompt on your phone to Approve or Deny.

• You can choose “Don’t ask again for 30 days” on trusted devices.

• If you ever get a prompt you didn’t initiate, press Deny immediately — it may mean someone else has your password.

• If you replace your phone, you’ll need to re-register MFA from a trusted computer (so keep your backup methods current).
