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 link to the bridge bot.
  3. Scan the QR code the bridge sends you.

Registering as the primary device

  1. Send register <phone> to the bridge bot. The phone should be in the international format with no spaces.
  2. Once you get the SMS verification code, send it to the bridge.
  3. To be able to participate in v2 groups, set a profile name with set-profile-name <name>.


Refer to the signald docs on dealing with captcha required errors. The bridge supports the same --captcha parameter as signaldctl, but it must be passed before the phone number instead of after (e.g. !signal register --captcha 03AOLTBLR... +12024561414). The signalcaptcha:// part must not be included.
