Is it possible to use such authorization?

Question

User identification

I have a website, I am making a mobile application on phonegap. Due to the lack of functionality, there were many problems with authorization. For example, authorization through social networks and third-party sites, which is tied to the site's domain, is a pain.
In general, I decided everything as follows:
In my application, I open my site and from it I go through authorization through social networks. The social network redirects the user back to my site, where I generate a token on the page, save it in the database and give it to the application. The application saves this token in local storage and sends it every time it accesses the server, which finds this token in the database and returns the necessary data.
That is, additional authorization did not appear for me, it remained the same as it was through the server part of the site.
Are there any pitfalls with this approach?

Answer 1

Pitfalls - in the store, most likely, they will not be allowed.
It is necessary to cut stand-alone authorization.
