Lock selected ChatGPT conversations

Before you try it

• Announced October 20. The guide checked October 22 lists Free, Go, Plus, Pro, Business, Enterprise and Edu, with gradual rollout; your account may not have it yet.
• Available on web, iOS, Android and the new ChatGPT desktop app for macOS and Windows. Eligible cloud ChatGPT conversations in Chat or Work can be locked; Codex and local Work conversations cannot. Healthcare is not supported.
• Locking changes visibility and access, not retention or model-improvement settings. It does not create end-to-end encryption or remove information already remembered from the conversation.
• A shared link created before locking can still expose its previously shared content. Delete that link separately if you want to stop access.
• Resetting a forgotten account PIN permanently deletes locked chats and content protected only by that PIN. Changing a known PIN does not delete them.

A small next step

Our suggested way to explore the change.

1. Review any shared links and existing memories associated with the conversation before trying the feature.
2. Use a sample eligible chat. Open its more-options menu, choose Lock chat and follow the confirmation and PIN prompts.
3. Find the chat under Projects > Locked chats and reopen it with your account PIN or supported device authentication. Use Lock now when finished.
4. Before sharing your screen or device, refresh other open clients and check the chat is hidden there too.
