Set up Microsoft Authenticator for work
Authenticator is how you approve work sign-ins on your phone. Set it up once and most logins become a tap.
- Install Microsoft Authenticator from the App Store or Google Play.
- On a computer, go to aka.ms/mfasetup and sign in with your work account.
- Choose to add a sign-in method and select Authenticator app, which shows a QR code.
- In the phone app, tap add account → Work or school → Scan a QR code, and scan the screen.
- Approve the test prompt; from now on, approve sign-ins by tapping the matching number on your phone.
Still stuck after those?
You’ve done the right thing by trying. Send whedo.it a quick note — what you tried, what you saw — and a senior pair of eyes will be on it the same business day.
