Private Rooms

Use a short-lived encrypted room when a handoff needs a small private conversation.

What a room is for

A room is for temporary discussion around a handoff. It is not a permanent team chat, knowledge base, or customer-support archive.

  • Use rooms for short-lived exchanges
  • Avoid secrets in normal chat tools
  • Burn or let rooms expire when the handoff is done

Participant limits

Private Rooms are paid-only to create. Pro remains a 1:1 room product. Pro workspaces and Enterprise can create bounded group rooms with higher participant and message limits.

  • Pro: 10 active rooms, 250 messages per room, 2 participants
  • Workspace: 50 active rooms, 500 messages per room, 10 participants
  • Enterprise: 200 active rooms, 1,000 messages per room, 25 participants

Passphrase-protected invites

A room passphrase wraps the room key in the browser fragment. The passphrase is not persisted by Shhhs. A wrong passphrase should not join the room because the local client cannot unwrap the room key.

  • Wrapped key in fragment
  • Passphrase shared out of band
  • Wrong passphrase blocks join
