How to do 2 different authorizations?

Question

Google

I have a website that works with api. During authorization, it gave a token, and then checked it, but now it decided to add authorization through Google. And how then so to authorize the user? The check is on the api port, and in order to enter the password and login, you have to follow another link from the site and the connection with the site is lost. Stuck at this point, doing this for the first time, I will be glad to any advice.

Hello, what is the purpose of google authentication (convenience or data usage)? Do you store information after "I have a site that works with api. During authorization, it gave a token, and then checked it"?
