I have an application for my client that uploads videos on youtube on behalf of my client.
What my client do is provide his user name and password in my app and then app uploads videos using Youtube DATA API V2(Username/password credentials).
But since username/password authentication mechanism is not available in V3, I have to change the user involvement that is required in the new Authorization mechanism. But my client is does not agree.
The question is, what if I continue to use API V2 and not switch to V3. Is there any chance that Google will stop V2 and I have to move to V3?
Is there any way I keep authenticating using credentials and not switch to OAuth 2.0?
