Harden gateway auth: avoid undefined/null tokens from configure

Solves a real misconfiguration trap where gateway.auth.token becomes a guessable literal string. Use sanitized input + reconfigure flow to force random token fallback.

GITHUBDiscovered 2026-02-14Author omair445

Prerequisites

OpenClaw CLI access on the host (can run configure and gateway commands).
Permission to restart gateway after config change.

Steps

Inspect current auth config and verify token is not empty/placeholder text.
Run interactive configure again and explicitly set a real token or leave blank for auto-generated random token.
Restart gateway and immediately test one authenticated request path.
If deployment uses scripts/templates, add validation to reject literal undefined/null before writing config.

Commands

openclaw configure --section gateway

openclaw gateway restart

openclaw gateway status

Verify

Gateway status is healthy and config no longer contains literal undefined/null auth values.

Caveats

Rotating token may invalidate existing clients; plan a short maintenance window.
Scripted deployments with env interpolation can still reintroduce bad strings if input validation is missing（需验证）.
