How to make authorization in web and mobile applications?

Question

Mobile development

In general, there are no problems with authorization. I generated a couple of tokens and you get access, and then you do a refresh. Easy.
The problem appeared when I didn’t enter the mobile application for several months, for example. The refresh is rotten and the user is thrown out.

I understand that the task is already with a beard, but tell me how the endless authorization on the mobile phone works. I can't find any information. Everywhere access and refresh.

and what's the problem? Well, increase the validity period
