ChatGPT's new Locked Chats feature has a major privacy catch

ChatGPT can hold a lot of knowledge about its users, acquired through deliberately personalizing the AI chatbot or by you simply leaving the memory feature on during conversations. OpenAI seems to think that might include details you'd rather a friend or family member didn't stumble across, and it has taken steps to ease those fears with its new Locked Chats feature. Locked Chats seals specific conversations with ChatGPT behind a four-digit PIN or biometric check on mobile devices. Open the menu under the three dots in the upper right of the chat window, tap "Lock Chat," and confirm. You'll need to make a four-digit PIN if you haven't already, or link it to the face or fingerprint you use to unlock your device. Also, be sure to remember your PIN.
