Instead of using push notifications for two-step verification, users can set up an Authenticator app to generate verification codes on their device that they can use to verify their identity. There is no internet connection required and no need to wait for texts or calls. These verification codes are valid for 30 seconds.
You can use any authenticator app that is available to you, but these instructions are specifically for the Microsoft Authenticator App.
