iOS Question OAuth2 with another user/password

[b4auser1]

I ported from B4A to B4i OAuth2 (Google API) authorization using WebView. It works, but I don't know how to provide a user with option to enter another user/password. I clean up refresh token, but I still don't see screen with login/password, just screen to confirm permissions. How to show screen with user/password ?

There is a revoke token API that you can call: https://developers.google.com/identity/protocols/OAuth2WebServer#offline

I saw this this API, but if there is no token, f.e. User uninstalled app and installed it again, then there is no token which can be used as a parameter of this API.

All data will be cleared when the user uninstall the app. So the WebView will show a non-cached page.
