Question

I have a asp.net mvc application. Now I want to add a sso with Microsoft. So there will be a button which offers the user the possibility to authenticate with Microsoft account. Upon clicking the button I want the user to login with a Microsoft account and then retrieve an access token which I can use for calling Microsoft Graph Api.
