How to make authorization in the Android application?

Question

Java

I have a server to which I send the entered data using a request and get back the Token and information and the user. How can I make it right so that the authorized state is saved and I don’t have to re-enter the login with a password every time I start it?

Answer 1

You can also implement JWT authorization (bearer token).
And then every time you start your application, instead of entering a login and password, you send a token to the server and authorize the user. The server on what at you is written? Is a framework being used?
For example, here is a solution for Spring + Spring Security
