Twitter API and reauthorization?

Question

OAuth

I may now ask a thing that lies on the surface, but has already broken the brain). So sorry in advance.
Do I understand correctly - after the user once gives the application access to his account, the Authorize Application to use your account page? shouldn't show up anymore? So why the hell do I see it over and over again in my applications? Has anyone experienced this? Tell me how to treat.

Answer 1

During authorization, the server returns an access token, for further work you need to use it
