Self-Service Guide
Setting Up Microsoft Authenticator
Multi-Factor Authentication (MFA) protects your work account. You will need both your computer and your smartphone to complete this four-phase setup.
To protect your account and company data, we are implementing Multi-Factor Authentication (MFA). Please follow all four phases in order to fully secure your account.
Phase 1 — Download the App on Your Phone
Before doing anything on your computer, grab your smartphone and download the official free app:
⚠ Important: Look for the official app published by Microsoft Corporation with the blue icon. Do not download paid third-party copycat apps — they will appear as sponsored results at the top of your search.
Phase 2 — Generate Your Setup QR Code on Your Computer
On your computer, open a web browser and go to:
aka.ms/mfasetup- Log in using your work email address and temporary password
- A prompt will appear stating "More information required" — click Next
- The screen will say "Start by getting the app" — since you already downloaded it in Phase 1, click Next
- Keep clicking Next until a large unique QR code appears on your screen
- Leave this QR code on your screen and pick up your phone
Phase 3 — Link Your Phone to Your Work Account
iPhone Users
- Open the Authenticator app on your iPhone
- Accept the privacy agreement if prompted
- Tap Add Account or the + icon in the top right
- Select Work or school account
- Tap Scan a QR code — allow camera access if prompted
- Hold your iPhone up to your computer screen and aim the camera over the QR code
Android Users
- Open the Authenticator app on your Android device
- Accept the initial privacy terms
- Tap Add account or tap the three dots menu
- Select Work or school account
- Tap Scan QR code — grant camera permission if prompted
- Hold your phone up to your computer screen and align the camera over the QR code
Phase 4 — Final Verification Test
- Once your phone scans the QR code, click Next on your computer
- Microsoft will send a test notification to your smartphone
- A 2-digit number will appear on your computer screen
- On your phone, enter that exact 2-digit number into the Authenticator app and tap Approve (or verify with Face ID / fingerprint)
✓ Setup Complete! Your account is now fully secured. Going forward, whenever you log into your work account from a new device you will enter your password and approve the notification that appears on your phone.
