SignIn to Youtube (Android App) with Gmail but without adding Account I want to Sign-In to YouTube Mobile App on Android phone with Gmail Account but without adding the Account to Phones Account list , cause if I add the Account to phone then the account also shows up in the Gmail App which I don't want. I have a separate Gmail Account for Email and Sync and I have a separate account for YouTube which I don't want to be listed anywhere in phone except in YouTube App.

Is there a way to to Sign-In to YouTube App using Gmail account but not adding the whole account to Phone.
You tube is Google owned and therefore, is closely related to the purchases you make, your viewing habits which are monitored by Google (read ad and revenue generation). So, the tight coupling is inevitable as answered here
That leaves you with the option of signing out of Gmail  (of the youtube related account) or  use alternative approaches like FireFox addon or IMAP approach so that you have mail access as also youtube stand alone


It's a workaround
