 Chat Server

In addition to using a native app, you can sign in to the W3C TAG Chat server (https://chat.w3ctag.org/) in your web browser ( Chrome,  Firefox, and  Safari)1.

Element Web Client

Installing a native Chat app on your mobile device allows you to receive notifications when people are trying to reach you even when you’re not using the app. Using the Chat server in a web browser requires the page to remain open in order to receive notifications.

The Chat server is your always-on, secure text/voice/video communication channel with your teams.

  • Text chat, voice, and video calls
  • One-to-one chats, small private groups, big public ones
  • Join or create rooms per topic, per group, per event
  • Messages are stored when you are offline and automatically sync when you reconnect
  • End-to-end encryption (e2e), no-one else can eavesdrop on your conversations, not even server admins
  • Users of other Matrix compatible homeservers can be invited to chat rooms

The Chat server uses Single Sign-On. Once you’ve signed in to SSO via any service, you’re signed into your Chat server account, and you won’t be re-prompted to log in again until you sign out or your SSO session expires.

The Chat server doesn’t yet support Single Sign-Out, though. That means that when you log out of the Chat server, your SSO session isn’t affected, you’re still logged in to other services.
