For organizations with YouTube Restricted Mode enabled, certain users have the ability to approve videos.

If your G Suite administrator gave you permission to approve YouTube content, you have unrestricted access to YouTube and can approve videos and channels for everyone signed in with their G Suite account in your organization to watch. 

1. Sign in to YouTube with your G Suite account.
2. Enter what you’re searching for and then filter the results by videos or channels. 
3. Click the video or channel that you want to approve.
4. Choose one or both of these options:
   • Below the video player, click Approve to approve the video for everyone. 
   • At the top of the channel page, click Approve to approve the channel for everyone.

Please note, if you are seeing this screen when attempting to approve a Youtube video, you are not signed in:
