ChatGPT now lets you lock your chats

OpenAI announced on Tuesday that users can now lock ChatGPT conversations to keep sensitive chats private when others may have access to their screen or device. Users can secure their locked chats with a four-digit PIN, or use Face ID or Touch ID on supported devices. Unlike the app’s Temporary Chats, which provide a separate session that doesn’t appear in chat history, users can return to Locked Chats at any time. The company says the feature is designed for situations where users might be discussing something personal or planning a surprise and want to keep those conversations private when handing their device to friends or family to show them something in another chat.
