ChatGPT Locked Chats Add a PIN Gate, Not Encryption
ChatGPT Locked Chats hides conversations behind a 4-digit PIN or biometrics, but it is not end-to-end encryption and PIN resets delete chats.
ChatGPT Locked Chats is a new option in OpenAI's chatbot that hides selected conversations from the regular sidebar history, pinned chats and search results. OpenAI began rolling out the feature on October 20, 2026, and access is expanding gradually by account. Reopening a locked chat requires a 4-digit account PIN, or Face ID, Touch ID or the Android device unlock on supported phones.
Locked conversations stay saved in the account and move into a dedicated section reached through Projects, under Locked chats. On web and desktop, the PIN is the only way in. On mobile, biometrics or the device unlock can replace it. OpenAI's help-center guide states that the feature is not end-to-end encryption, and that it leaves retention and model-training settings unchanged.
What ChatGPT Locked Chats Protect Against
The feature guards against people who can see your screen or pick up your device. It does not guard against OpenAI. The company can still access locked chats for safety and compliance purposes, so the lock sits on the interface, not on the stored data.
Locking a chat also leaves earlier memory in place. OpenAI notes that locking does not remove information ChatGPT already remembered before the chat was locked. When memory is enabled, locked chats draw on a separate memory shared among locked chats, and new details entered after locking stay out of the memory used in regular chats.
The feature also differs from Temporary Chats, which ChatGPT already offered as private conversations that are not saved by default. Locked chats are kept in history, so they can be resumed at any point, but they are hidden from the places where a second person would normally look.
The PIN Reset Trade-Off
The sharpest cost sits in recovery. Resetting a forgotten PIN permanently deletes every locked conversation and its associated files. The feature does not create a separate encrypted vault, so there is no second key that opens the chats if the PIN is lost.
That makes the lock a convenience control with a hard failure mode. A user who keeps the only copy of important material inside a locked chat risks losing it in a single forgotten-PIN event. Users who need durable records should keep copies outside the chat before they lock it.
Availability is gradual. The sources do not list a separate price for the feature, and the rollout reaches accounts in stages, so some users may not see the option yet.
Verdict for Users
Locked Chats fits a narrow job: keeping a conversation off the screen during a shared-device moment, such as a family laptop or a screen share. It does not fit material that needs encryption or protection from the provider, because OpenAI retains access and the feature is not end-to-end encrypted. Set a PIN you will not forget, and export anything you cannot afford to lose.
Why this matters
The feature addresses privacy from people nearby, not privacy from the platform. Users who treat a locked chat as a secure vault could lose data or assume protections the company has not provided.
