If you are trying to access users google drive accounts files stored on that then you need to use Oauth2.
However if you are trying to access a central google drive account one that you as the developer has controller over you should look into service accounts. Service accounts are like a dummy user it has its own drive account and you can share a folder on your drive account with it. Its pre authorized so it always has access you dont have to worry about authenticating it.
