Firstly, no OAuth or other things supported in the server-side, just a normal username-password database querying.
I want to implement an android client for the web site. My questions are:
- How to login safely? with HTTPS?
- How to store user login information safely in the phone to make user login without any input in the next time.
- If user do some actions after login, how to id himself? how to keep the session? By copy and resend some cookies like "jsessionid" ?
