What is the logic of authorization through social networks on a site with laravel jwt?

Question

Web development

The site has a standard registration and login via email-password.

Now you need to make authorization through social networks, for example vk.
On the server, I received vk user data - id, first_name, last_name.

At this point, I'm a little confused.
1. This data must be saved in the database.
2. After saving the data, how to authorize the user? if I have authorization through email - password
3. If the user logs in through another social network, he will have 2 entries in the database.

I can not understand the logic of this process.

Abisnyayu:
1. You save the data in the database - the user in one table, binding to the social network in another.
2. Authenticate (this is not authorization, when you already understand the difference) the user by id in your database. As - it is written in the documentation.
3. You also need to request soap from the social network, it will be the “unifying” key - rarely does anyone register on different social networks with different soaps. Well, if so, then nothing can be done.
