id - received from VK
userid - your users.
And your table.
users
id - your user.
If the user first came to your site, then create an internal (your) user and an entry in authusers, where you link yours and from the social. networks.

If the user logs in through the social. network, then check if there is one by VK-ID, get your user ID and then work with yours.
