Enable multi-factor authentication on your Microsoft account

MFA stops over 99% of account-compromise attacks. If your IT admin has not already enforced it, you can enable it yourself.

Set up MFA with the Microsoft Authenticator app (recommended)

1. On your PC, go to aka.ms/mfasetup and sign in with your work account.
2. Select Add sign-in method → Authenticator app → Next.
3. On your phone, install the Microsoft Authenticator app (iOS App Store or Google Play).
4. In the app, tap + → Work or school account → Scan QR code.
5. Scan the QR code shown on your PC screen → Next.
6. Approve the test notification that appears on your phone → Next → Done.

Set up MFA with a phone number (backup)

1. At aka.ms/mfasetup, select Add sign-in method → Phone.
2. Enter your mobile number and choose Text me a code or Call me.
3. Enter the code sent to your phone → Confirm.

What happens at sign-in

After entering your password, Microsoft will ask you to approve a push notification in the Authenticator app (or enter a code from a text message). Approving it completes the sign-in.

If you lose your phone

Call the help desk immediately: (972) 961-7711 Option 2. They can reset your MFA methods so you can access your account from a new device.

> Security tip: Never approve an MFA prompt you did not trigger yourself. An unexpected prompt means someone is trying your password — reject it and report it.
