You cannot log out of an account in the YouTube Music app at present. However, you may change accounts in the account menu. You can also completely terminate your membership by deleting and reinstalling the YouTube Music app.
From the main screen, select Manage accounts from the drop-down menu. Select a profile image for your device by tapping here. If you don’t see this option, make sure you’ve set up at least one account on your device and that it’s linked to Facebook.
When logged into a Google account on an Android device and using the YouTube app, users will see that the sign-out option has been replaced with “Turn on Incognito.” When Incognito Mode is switched on, the YouTube app reminds you at the bottom of the screen that you’re incognito.
