I'm setting up a REST API project using ASP.NET Core Identity for user management only (so this will be my identity provider). What I would like to also add is multi factor authentication (I would prefer Microsoft's authenticator). I don't know how to do that exactly and I could not find anything on the web which I could use.
Did anyone had to implement this and if so willing to share a repo , code sample or something ?
My app consists from an asp.net core backend and a react app.
