Takes about 5 minutes. You'll need your phone and your Kirk's Global email login.
On your phone, download Microsoft Authenticator from the App Store (iPhone) or Google Play (Android). It's free and takes under a minute to install.
Go to aka.ms/mfasetup on your computer and sign in with your usual work email and password. Choose "Set up using an app" when prompted.
Your screen will show a QR code. Open the Authenticator app, tap the + icon, choose "Work or school account," and scan the code with your phone's camera.
Your computer will show a two-digit number. Type that number into the app on your phone to confirm the match. That's it. MFA is now active on your account.
After entering your password, you'll get a notification on your phone, just tap "Approve." If you ever get a prompt you didn't trigger yourself, decline it and contact the helpdesk immediately.
