CURL+PHP Google authorization?

Question

Google

Good day. Started learning CURL. There was a problem of authorization through CURL in Google account on login and the password! Wherever I go, everywhere they write about the Google API. There seems to be an authorization method for login / pass. Do you really need some kind of secret_key and secret_id? Something with tokens was written. In general, knowledgeable people will understand. Can you briefly describe the principle of applying these techniques?

Answer 1

Google recommends using their client libraries for OAuth authentication.
It is most likely impossible to imitate a browser with cURL and PHP. If you really want to - look towards outdated mobile browsers without JS - how Google authorization looks from them.
