How do I create a Xamarin Forms login app to consume an api to authenticate the user using the MVVM Model?

The code should contain MVVM pattern architecture

if you are using oauth, then typically a webview is required. you will want a client sdk for this as coding the login is a little complex. see the web authenticator
