When choosing a chat app as OpenClaw’s channel, it’s easy to feel stuck: WhatsApp, Signal, Telegram, Discord—everything works, but everything feels like a compromise. WhatsApp and Signal typically rely on multi-device sync: OpenClaw is treated as another linked device under your existing account. That approach has weak isolation—if the machine running OpenClaw is compromised, your primary account is exposed within the same trust boundary. Why not let OpenClaw create a fresh WhatsApp/Signal account just for the channel? Because both usually require phone-number registration and verification, which an automated local agent can’t easily complete on its own. Telegram and Discord takes a different route. You create a bot first, get a bot token, and give that token to OpenClaw. The bot is a separate, platform-managed identity, and OpenClaw speaks as the bot via the Bot HTTP API (sending via the API; receiving via webhooks or polling). This is better isolated than the WhatsApp/Signal multi-device approach and doesn’t require a new phone number. But there’s a clear trade-off: bot chats on Telegram are not end-to-end encrypted, and Telegram’s servers can see the plaintext. (Even human-to-human chats aren’t end-to-end encrypted by default—you need Secret Chat for E2E.)
