If yourPeertubeinstance allows joining chat with [XMPP clients](https://livingston.frama.io/peertube-plugin-livechat/documentation/admin/advanced/xmpp_clients/), users using such clients will see the terms as chat messages, comming from a "Peertube" account.When you update terms, they will receive a new message with the update termscontent.
If you are not logged in on the Peertubeinstance where you are watching the video, you will automatically join the chat.You will be assigned a random nickname (something like "Anonymous 12345").
The Peertubeinstance can configure external authentication providers (Mastodon accounts, Google accounts, ...).In such case, you will see a "{{% livechat_label login_using_external_account %}}" button, that will open a dialog modal.In this dialog modal, there will be some buttons to connect using a remoteaccount.
