Using CM Chat

Guests

A guest is an outside person, such as a client, invited to take part in specific channels only.

What a guest can do

  • Read and write in the channels they were added to.
  • Send direct messages to people who share a channel with them.
  • Share files in their channels and search those channels.
  • Use their own profile and devices screens.

What a guest cannot do

  • See any channel they were not added to. Other channels, public or private, are invisible to them.
  • Browse the list of channels.
  • Create channels or add people.
  • See the whole list of people. A guest sees only people who share a channel with them.
  • Use the admin console.

Shorter sign-in time

Guests are signed out sooner than members. By default, 12 hours without use or 7 days in total. A guest may also have an end date: after that day the account stops working. An admin can change the end date.

If you are a guest

You accept an invitation and sign in like everyone else, with the code we email you. A second step (a passkey or authenticator app) is optional unless the workspace owner requires it. See Accepting an invitation.

If you are an admin

See Admin: Invitations to invite a guest and Admin: People to change their end date. Only admins can add a guest to a channel.
