    Open the Authenticator app.

💡 If you have not used Authenticator before, you might first be prompted to sign into a personal Microsoft account to facilitate backing up your Authenticator codes. If you have a personal Microsoft account, we recommend doing this. If not, you can create one or skip this process.

  • In the menu, click Add account.
  • Choose “Work or school account”.
  • Tap Scan a QR code.
  • Use your camera to scan the QR code presented on your computer screen.

💡 Your phone may ask you to give Authenticator permission to use your camera. You need to allow this.

  • On your computer, click Next. Note the two-digit number presented on the computer screen. In this case, 28.
  • Back on your phone, the request will pop-up either on your phone screen or as a notification.
  • Tap on the notification if necessary, then enter the two digit number, then tap YES (or the tick button) to approve the login.
  • Your computer will now automatically confirm the approval. Click Next.
  • Setup is complete.

In future when you sign into a new device, or periodically thereafter you may be asked to approve a sign in request on your phone after having entered your password.

⚠️ If you ever receive a sign in approval on your phone when you are NOT signing in, report the incident to your administrator or support team.
