How 2FA Works
Your account uses Microsoft Authenticator for two-factor authentication (2FA). After you enter your password, you'll need to approve the sign-in on your phone using the Authenticator app. A manager will set up your Authenticator during onboarding.
Don't Uninstall Authenticator
Once Authenticator is set up, don't uninstall it or you won't be able to sign in to your work apps. If you get a new phone, set up Authenticator on the new phone before wiping the old one, or contact Robert/your manager to reset your 2FA.
