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

This method is strongly discouraged, as it's harder to recover if something goes wrong, and you won't be able to migrate the registration when the bridge is rewritten in Go. If you don't want to use the official signal apps, you could use signal-cli to register and link the bridge to it.

Registration instructions
  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 signal-recaptcha-v2.03AOLTBLR... +12024561414). The signalcaptcha:// prefix must not be included, but everything after it must be.
