I am creating an application xamarin forms mvvm using SQL lite and Web Api to get the data from the database.
I have a login Page where the user logs in by checking the database for the UserName and Password.
I want to use the user Email later, but I am not sure which is the right way to do that. The email is saved in the database and I can get it from the database only if I know the username and password. I do not want to force the user to re-type his/her credentials.
Which is the right way to achieve that?
