ChatGPT 推出聊天锁定功能，支持 PIN 码与 Face ID 保护对话
ChatGPT now lets you lock your chats
- 1OpenAI 推出 ChatGPT 锁定对话功能，可用四位 PIN 码或 Face ID、Touch ID 保护敏感对话
- 2锁定对话移入独立 Locked Chats 区域，与常规历史、置顶对话和搜索结果隔离，并拥有独立记忆
- 3OpenAI 说明锁定不构成端到端加密，不改变保留时长，也不删除锁定前模型已记住的信息
- 4功能覆盖 Free 至 Enterprise、Edu 各套餐，ChatGPT for Healthcare 不支持，周二起逐步推送
锁定功能挡的是设备被他人接触时的窥视，不改变数据留存与训练设置，企业不能把它当作数据安全边界。
- 影响：员工在共用设备上讨论敏感话题多了遮挡手段；但对话保留时长、记忆和训练退出设置均不受影响，合规仍需依靠既有数据管控；医疗版不开放。
- 参考：可考虑提醒共用设备的员工用锁定功能遮挡敏感对话；值得核对自身数据保留与训练退出策略，明确锁定不构成加密也不改变留存，不要把它列入安全边界依据。
- 依据：功能细节与限制均为 OpenAI 官方口径，暂无独立验证；含锁定不构成端到端加密、不改变保留时长、部分聊天类型不支持等。
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.
The addition of locked chats adds a new layer of privacy to ChatGPT, as the app is increasingly used for personal conversations. Of course, while locking a chat can limit access, it doesn’t address concerns about how sensitive information is stored or handled.
OpenAI notes that locking a chat doesn’t create end-to-end encryption or a separate encrypted vault, change how long it retains the chat, remove information that ChatGPT remembered before a chat was locked, or change the “Improve the model for everyone” setting.
Once users lock a chat, it moves to a dedicated “Locked Chats” section, where it’s kept separate from regular chat history, pinned conversations, and chat search results.
With Memory enabled, Locked Chats has its own separate memory shared across conversations within the section. New messages sent after locking a chat can update that memory, but don’t update regular Memory. That means new information from locked chats won’t leak into regular chats.
OpenAI says resetting a PIN permanently deletes all locked chats, files, and other content protected by the previous PIN.
Additionally, the Locked Chats option isn’t available for temporary chats, archived chats, group chats, chats created from a shared link, chats with scheduled tasks, and chats with meeting recordings.
Locked Chats will be available to users on ChatGPT Free, Go, Plus, Pro, Business, Enterprise, and Edu plans. The company notes that the feature is not available on ChatGPT for Healthcare. The feature is starting to roll out on Tuesday, so it may not be live yet for all users.
