How to implement authorization on the site through the Android application?

Question

PHP

I work on Android Studio - Java, I want to create an application for the site, but I don’t quite understand how to implement authorization through the application, if everything is clear with the browser, just open a session in php, then I don’t have such a good understanding of how to implement such functionality.
I'd be grateful for any hints or examples!

Answer 1

In fact, everything is simple, there are of course different approaches, libraries ─ OAuth 2.0, OAuth, etc. ... but this is not always necessary
if simplifying, the server simply sends a token during authorization (just a string, the lifetime of the token and other logic on the server's conscience)
Each application request to the server is signed with this token, there are options ─ someone writes it in the header, someone just passes it as a parameter ....
Quite a viable option, cheap and cheerful )

Answer 2

look for similar questions on the toaster, we analyzed authorization options and ways to create tokens for api requests
