title: Azure Active Directory - OAuth Authentication with Authorization Code Grant Flow and mobile
body: <p>I have a Web API that uses Azure AD OAuth for authentication,  that is consumed by a mobile client (android, iOS) and there are a functional requirement to avoid the user to enter again his credentials if he wants to use the application when the token and refresh token has expired. How could be the best way for handling this with Authorization Code Grant Flow ? Thanks a lot.</p>
