Authenticator App

The authenticator app installed on your smart phone or device is the easiest and most secure method of receiving your second factor when logging into Office 365 or any other Houston Methodist application that uses Azure authentication.

The instructions provided here are for replacing your current SMS texting method with the Microsoft Authenticator app for the second factor. 

Microsoft Authenticator is preferred but any authenticator app such as Google authenticator, will work just fine.
