Security & Safety Best Practices for OpenClaw.
1. Isolate Access
Never use a primary personal phone number for AI automation. Operating a SecondSim line ensures personal contacts, call history, and private chats remain strictly separated.
2. Secure Gateway
Protect your agent bridge from public exposure with local binding and SSH tunneling:
3. Isolated Workspace
Run your OpenClaw deployment within an isolated directory (e.g. .openclaw) to avoid conflicting permissions or accidental data leaks.
