Signal Integration

Signal is the most privacy-focused channel for OpenClaw. All messages are end-to-end encrypted, and combined with OpenClaw's local-first approach, your AI conversations are truly private.

Prerequisites

A Signal account with a phone number
Signal CLI installed on your system
OpenClaw installed and configured

Setting Up Signal CLI

Signal doesn't have a public bot API, so OpenClaw uses Signal CLI — an unofficial command-line client.

Install Signal CLI

# macOS
brew install signal-cli

# Linux
# Download from the signal-cli GitHub releases

Register or Link

Option A: Register a new number

signal-cli -u +1YOUR_NUMBER register
signal-cli -u +1YOUR_NUMBER verify CODE

Option B: Link to existing Signal account

signal-cli link -n "OpenClaw"
# Scan the QR code with your Signal app

Configure OpenClaw

{
  "channels": {
    "signal": {
      "enabled": true,
      "number": "+1YOUR_NUMBER"
    }
  }
}

Privacy Benefits

End-to-end encryption — Messages encrypted in transit
Local processing — OpenClaw processes on your device
No metadata — Signal minimizes metadata collection
Open source — Both Signal and OpenClaw are fully auditable

Limitations

Signal CLI can be less reliable than official APIs
Group support is limited
No rich formatting (Signal uses plain text)
Linked device sessions may need periodic refresh

Best For

Signal + OpenClaw is ideal for:

Privacy-conscious users who want AI assistance
Sensitive conversations that need encryption
Users who already rely on Signal as their primary messenger
