Authentication

  1. Open a private chat with the bridge bot. Usually @signalbot:your.server

Linking as secondary device

  1. Go to "Linked Devices" in the Signal app settings and add a new device.
  2. Send login to the bridge bot.
  3. Scan the QR code the bridge sends you.

Registering as the primary device

Registering as the primary device is no longer supported. If you don't want to use the official signal apps, you could use signal-cli to register and link the bridge to it.
