How to correctly implement the authorization and storage of user data of VK API?

Question

In contact with

I made user authorization in VK, through oAuth.
I would like to know how to properly store data, that is, the user's token in the database, is it worth encrypting?
How to correctly implement sessions and bind cookies so that the user does not need to relogin every time, but the data is saved?
Or, during authorization, each time to receive a new user token for interaction?
Thanks in advance)

Answer 1

The user token does not need to be received every time, the data can be safely stored in the database.
Do you have any cms?
