YouTube Comments
Read held comments, reply yourself and moderate your channel
Without it: Public comments can still be read with your YouTube key; held comments, replies and moderation stay off.
Comments uses the same Google project as your YouTube key: everything is set up in Settings → YouTube with one step-by-step guide, so your channel's comment reads and replies use your own free daily allowance. Only the Owner (with two-step login on) can connect or disconnect; Admins can read and reply.
Steps
-
1Set up your own Google project
Open Settings → YouTube and follow the guide: create your project, allow the YouTube permission, publish your app, create your sign-in client and paste its client ID and secret, then press Connect with Google and choose the exact channel set for this website. Google's consent wording also mentions videos and captions; the website uses it only for comments now and, later, for reading your captions. Nothing is posted until you press Send reply.

2Check or disconnect
Settings → YouTube shows a live check of your sign-in client, the connection and the channel. Disconnect there deletes the saved sign-in details at once and asks Google to remove access. You can also remove access in your Google account permissions.
Comment text and author details are read live and never stored. The connection is checked daily; one that can't be checked for 30 days is removed. Disconnecting never deletes comments on YouTube.
In your dashboard: Settings → Connections → YouTube Comments → Set up. Provider steps checked Nov 9, 2026.
