How to login to Google API OAuth2 from PHP console script?

Question

Google

Here is what the documentation suggests to do (all scripts start with the same authorization strings):
https://developers.google.com/youtube/v3/code_samp...
That is, CLIENT_ID and CLIENT_SECRET are taken,
Sent to https://accounts.google .com/o/oauth2/auth
A page appears on which you enter your login, password, select a subaccount if you have several pages of Google+ or Youtube channels.
The response is returned in the GET parameters of the script specified in the RedirectUri
. And I need a console script to do all this by cron without a browser and a web server.
That is, the script must log in, select the desired subaccount and all that needs to be done.
How to do it?
PS If you select non-UI (cron,cli) when creating keys for Youtube API, then the following message is displayed:
User data cannot be accessed from a platform without a UI because it requires user interaction for sign-in.
So you need to look for exactly some kind of option with OAuth. Examples in Python, for example, also require authorization in the browser, but 1 time, then they create a JSON file and then work with it without re-authorization

Answer 1

Save cookies and give cookies to the server - the only browser emulation. well, curl

Answer 2

I did something similar for VK.
Look at the idea and do something similar.
