Slack lets workspaces invite guests with limited access instead of full members. Tightknit supports both guest types: they sync automatically and can access your companion site without any manual invitation.

​
Guest Account Types

Slack offers two kinds of guest accounts, both available on Slack’s paid plans. For details on inviting and managing guests, see Slack’s documentation on guest accounts.
Guest typeAccess in Slack
Multi-channel guestCan be added to multiple specific channels you choose.
Single-channel guestHas access to a single channel only.
Guests belong to your own Slack workspace. They are different from external users in Slack Connect channels, who belong to a separate workspace and are handled differently.

​
Do Guests Get Access Automatically?

Yes. Guests are added automatically, with no manual invitation step. Single-channel and multi-channel guests are treated the same as full members:
  1. Tightknit’s profile sync regularly pulls every user in your Slack workspace, including guests, and creates a member profile for each one.
  2. Because a guest has a member profile, they can sign in to your companion site with Slack right away.
You do not need to invite guests to the companion site separately. As long as a guest is part of your Slack workspace, they are part of your Tightknit community.

​
What Guests Can Do on the Companion Site

Once a guest has a profile, Tightknit treats them like any other member:
  • Profiles sync the same way as full members. A guest’s profile is created or updated when they join, author a synced message, or are @mentioned in a synced message. See the Sync Guide for the full list of triggers.
  • Posts and comments sync when a guest sends a message in a channel that is connected to a Tightknit Feed.
  • Guests count toward your community member count, which Tightknit pulls weekly from the number of users in your Slack workspace.
A guest’s limited channel access in Slack does not carry over as a restriction on the companion site. Guests browse the companion site like any other member, subject to the same Feed visibility settings that apply to everyone. A guest does not need Slack access to a channel in order to view the Feed connected to it on the companion site.
A guest only contributes content from the channels they can access in Slack. If a guest has access to a channel that is not connected to a Tightknit Feed, their activity in that channel does not sync.

​
Guests vs. Slack Connect Users

It is easy to confuse guests with external users in Slack Connect channels. The difference determines whether Tightknit syncs them:
  • Guests are members of your workspace with restricted channel access. Tightknit syncs them automatically, like any other member.
  • Slack Connect users belong to a different workspace entirely. Tightknit ignores their messages and profiles unless you configure Slack Connect support. See Slack Connect for details.
