Can I hide my YouTube link in my Google+ profile and disassociate the two?
Google+ Help Official Answer
The only information that is always public is your profile name, your profile image and cover photo, and the link to the YouTube channel connected to your Google+ profile or page.
Therefore hiding YouTube link from the Google+ Profile is not possible at the moment.
You have to disconnect your YouTube channel from Google+.
- Go to YouTube Settings
- Click on "Disconnect channel from Google+" (next to your avatar)
- On the next page, tick "I understand that my channel will be renamed."
- Click "Rename Channel."
Account Management → Remove YouTube Content > Hide my profile
Check five boxes
You're good to go!
Took me forever to find this and I can't figure out how to re-enable it just yet—that is, if you wanted to.
