OpenAI Introduces PIN-Protected Locked Chats for Enhanced Privacy
Users can now secure individual ChatGPT conversations behind a four-digit PIN or biometric authentication.
1New Privacy Control Mechanism
OpenAI has launched a Locked Chats feature allowing users to secure specific conversations with a four-digit PIN. This functionality is designed to prevent casual observers from viewing sensitive chat history when sharing a device. Users can also leverage biometric methods like Face ID or Touch ID on supported mobile devices for faster access.
2Operational Workflow and Storage
Once a conversation is locked, it is moved to a dedicated 'Locked chats' section, disappearing from standard history, pinned lists, and search results. Users can continue interacting with these chats without moving them back to the main history. This provides a discreet way to manage ongoing personal discussions or sensitive research projects.
3Impact on ChatGPT Projects
Locking a conversation currently removes it from its original Project. Consequently, the chat loses access to that specific project's instructions, files, and memory. Even if the user unlocks the conversation later, it returns to the regular history rather than rejoining its previous project, requiring users to manually re-associate the chat if needed.
4Device-Specific Authentication Rules
Biometric authentication settings are device-specific and do not sync across platforms. Enabling fingerprint or face recognition on a Samsung Galaxy or Google Pixel does not automatically activate it on other devices. The four-digit account PIN remains the universal backup method, ensuring consistent access control across the web, desktop, and mobile applications.
5Automatic Session Timeout Protocols
To maintain security, access to locked chats expires automatically after one minute of inactivity on mobile devices. On the web, refreshing the page or closing the browser tab terminates the session. These automated relocking mechanisms ensure that sensitive information remains protected even if a user forgets to manually secure the interface after use.
6Limitations on Shared Content
Locking a conversation does not revoke access for users who already possess a shared link to that chat. Furthermore, users cannot archive, pin, move, or share a conversation while it remains in the locked state. You must permanently unlock the chat to perform these administrative actions or to modify its sharing status.
7Memory and Data Persistence
Locked chats do not provide end-to-end encryption or create an isolated vault. Existing memory remains accessible to locked chats, and new memories created within them may be shared with other locked conversations. However, regular chats do not automatically receive new memories generated inside the protected environment, maintaining a degree of data separation.
8Workplace and Compliance Considerations
For Enterprise and Edu accounts, locked chats remain subject to organizational retention and compliance policies. Workspace administrators cannot reset user PINs or unlock chats, but authorized compliance systems may still access the data. Users should avoid storing sensitive credentials like passwords or banking information, as this feature is primarily an access-control tool.
9PIN Recovery and Data Loss
If a user forgets their PIN, resetting it triggers the permanent deletion of all locked chats, including associated files and memories. This process is irreversible, and OpenAI support cannot recover the lost content. Users must verify their identity before proceeding with a reset, which serves as a final safeguard for protected information.
10Strategic Utility of Privacy Features
Locked Chats offer a practical solution for users managing personal advice or sensitive planning within AI interfaces. While this improves discretion, it functions as a convenience feature rather than a comprehensive security guarantee. Users should continue to evaluate their data sharing habits, especially regarding model training settings and the sensitivity of uploaded content.
