-### Security considerations
+## Security recommendations
 
 - Prefer authenticated tunnels during normal development
 - Only enable anonymous access for endpoints that are safe to expose publicly
 - Treat public tunnel URLs as temporary & untrusted (rate limit / validate input server-side)

+## Tunnel lifecycle
 
 Dev tunnels automatically:
 
 - Install the devtunnel CLI if not already available
 - Ensure the user is logged in to the dev tunnels service
 - Create and manage tunnel lifecycle
 - Clean up unmodeled ports from previous runs

 Tunnels will expire after not being hosted for 30 days by default, so they won't be forcibly deleted when the resource or AppHost is stopped.
