ChatGPT adds a lock feature for individual chats

On October 20, 2026, OpenAI rolled out a chat-locking feature for ChatGPT that lets users restrict access to individual conversations. The mechanic is straightforward: a user can lock a specific chat so that anyone else picking up the same device cannot open it, while other chats remain visible. OpenAI framed the use case around everyday device-sharing moments, such as handing a phone to a friend to show them a different conversation, or keeping a surprise plan hidden from a family member.

The feature is narrower in scope than a full account lock or a guest mode, targeting the specific gap between full device access and full privacy. That framing matters because it signals where OpenAI sees friction in day-to-day ChatGPT use: not just professional or sensitive data concerns, but ordinary social situations. Whether this is a meaningful privacy addition or a surface-level convenience depends partly on how the locking mechanism is implemented, including whether it relies on a PIN, biometrics, or simply the account password, details OpenAI had not spelled out in the initial announcement.

No reactions from the Pro-AI, Anti-AI, or Middle Ground camps had been published at the time of writing. Typically, Pro-AI voices would welcome the feature as evidence that OpenAI is iterating on user experience and treating privacy as a practical concern rather than an afterthought. Anti-AI commentators would likely raise questions about what the lock does not protect, pointing out that locking a chat on-screen does nothing to prevent OpenAI from retaining the conversation on its servers. A Middle Ground perspective would probably treat the feature as useful but limited, a small convenience that does not substitute for deeper privacy controls like end-to-end encryption or robust data deletion options.

The detail worth watching is how OpenAI documents the lock mechanism itself. If the company publishes a support page or privacy explainer clarifying whether locked chats receive any additional server-side protection, or whether the lock is purely a display-level restriction, that would determine whether the feature holds up to the more pointed questions the Anti-AI camp is expected to raise.
