I have a website and my visitors can register and they can use their username and password to login to their account.
My website is based on asp.net MVC and Microsoft SQL Server.
I want to develop an android app for my website.
On this scenario user can register and login to their account from this android app too.
I 'm new on android studio but I know that I should have a web service on my server side to use it on my app to handle some works like registering, login ,...etc.
I don't know how to store member's login information after they entered their username and password on my app on phone.
What is the best option on my case?
1- Account Authenticator like this post
2- Shared Preference like this post
3- Store authentication info on SQL Light (manually)
