ChatGPT 新增鎖定聊天功能，支持 4 位數字 PIN
openai 為 chatgpt 引入鎖定聊天功能，允許用戶使用 4 位數字 PIN 或生物識別技術保護敏感對話。
openai introduced a new feature for chatgpt, allowing users to lock conversations to maintain privacy. locked chats can be secured with a 4-digit pin, face id, or touch id on supported devices. this feature is intended for situations where users discuss personal matters or plan surprises and want to keep those conversations private when sharing their device. locked chats are stored in a separate section, with their own memory that doesn't interact with regular chat history. the feature is rolling out to all chatgpt users, including free, paid, and enterprise plans, but is not available for temporary chats, group chats, or chats with scheduled tasks.
