For the Google Drive Python API, in all the tutorials I have seen, they require
users to create a project in their Google Dashboard, before obtaining a client ID and a client secret json file. I've been researching both the default Google Drive API and the pydrive module.
Is there a way for users to simply login to their Google Account with username and password,
without having to create a project? So once they login to their Google Account, they are free to
access all files in their Google Drive?
It's not possible to use the Drive API without creating a GCP project for the application. Otherwise Google has no idea what application is requesting access, and what scope of account access it should have.
Using simply a username and password to log in is not possible. You need to create a project and use OAuth.
