title: Does Microsoft Authenticator require Azure AD?
body: <p>My scenario is that I'm looking to implement <a href="https://www.microsoft.com/en-us/account/authenticator" rel="nofollow noreferrer">Microsoft Authenticator</a> in my ASP.NET C# web application in order to provide 2FA.</p>
  
  <p>All my user data is self contained within our SQL Server database.</p>
  
  <p>Is it possible to utilise Microsoft Authenticator without also using a service such as <a href="https://azure.microsoft.com/en-us/services/active-directory-b2c/" rel="nofollow noreferrer">Azure Active Directory B2C</a>?</p>
  
  <p>Alternatively we are thinking of utilising <a href="https://developers.google.com/api-client-library/dotnet/guide/aaa_oauth#web_applications" rel="nofollow noreferrer">Google</a>'s offering or <a href="https://www.twilio.com/" rel="nofollow noreferrer">Twilio</a> however our client's IT resource seemed to think that it would be possible to use Microsoft Authenticator without Azure Directory.</p>
  
  <p>Any guidance much appreciated.</p>
