ChatGPT Locked Chats: PIN & Fingerprint Protection Coming

OpenAI appears to be developing a new privacy feature for ChatGPT. This feature could allow users to lock individual conversations with a PIN, fingerprint, or other device authentication. Hidden references in the latest Android version of ChatGPT suggest this development is underway. These references, found in version 1.2026.230, mention "locked chats" and an option to "protect chats." The purpose is to hide a conversation's title and contents from the normal sidebar, chat history, and search results. This means users could hide existing conversations and require authentication to access them. ChatGPT already offers Temporary Chats, but these are not meant to be retained like ordinary chats. This new locked-chat system could offer a middle ground, allowing users to keep sensitive conversations stored but hidden. This feature could be useful for anyone using ChatGPT on shared devices, protecting personal or sensitive information.
