What does OpenAI’s Codex mobile “remote control” reveal about where it draws the security perimeter?
Take-away Codex’s “remote control” sets the boundary at a managed, sandboxed runtime: secrets stay on the host while the agent gets tightly scoped SSH + egress allowlists.
OpenAI’s Codex mobile "remote control" feature indicates that the security perimeter is defined such that files, credentials, permissions, and local setup remain on the local machine, with secure connectivity preventing access via the public Internet [1]. The system ensures that remote SSH access is possible but only to managed environments, preventing direct public access [1]. Additionally, the security perimeter incorporates auto-approval for low-risk tasks to reduce interruptions and limits network reachability through sandboxing and network policies, restricting outbound access to only expected destinations [2].
