Your channel and Google+
Most people don't need Google+ to use YouTube.
If you’re comfortable using the name and photo you’ve selected for your Google account on YouTube, you no longer need to have a Google+ profile on your account. You can create a channel and use all YouTube features without Google+. If you already have a Google+ profile, it won't affect your channel whether you keep or remove your Google+ profile.
Reasons you might still need Google+ connected to your YouTube channel
- If you want to use a different name and photo on YouTube than the name and photo you’ve chosen for your Google account, your channel should be connected to a Google+ page.
When connected to a Google+ page, your YouTube channel gets its name and channel icon from the connected page, instead of from your Google account. Any name and photo changes will apply to both the Google+ page and the YouTube channel.
-
If you want multiple managers to have access to your channel without sharing passwords, you can use admin features with a Google+ page.
Comment notifications
If you want to get comment notifications through the notification bell , your account needs to have an associated Google+ profile or page.
What if I never connected my channel to Google+?
If you’d like to use the same name and photo that you’ve selected for your Google account on YouTube, consider confirming your name so you can regain some features on YouTube, like commenting.
