ChatGPT Chat Lock Adds Private Locked Conversations for Personal Chats
TL;DR
- OpenAI is rolling out Chat Lock for ChatGPT, letting users hide sensitive conversations behind Face ID, fingerprint, or passcode authentication.
- Locked chats are moved to a dedicated Private section and stay hidden from chat history, making it ideal for personal advice, surprise planning, and shared devices.
- The feature is rolling out now on mobile, with more platform support expected, as part of OpenAI's broader push toward privacy-focused controls.
What Is ChatGPT Chat Lock?
OpenAI has started rolling out a new privacy feature called Chat Lock, designed to give ChatGPT users more control over sensitive conversations.
Similar to app-lock features seen in messaging apps like WhatsApp, Chat Lock lets you lock any individual chat thread so it can only be reopened with biometric authentication or your device passcode, such as Face ID, fingerprint unlock, or PIN.
Once locked, the conversation is removed from your main chat history and moved to a separate Locked or Private section at the top of the sidebar. Anyone opening ChatGPT on your phone without your authentication won't be able to preview, search, or accidentally open those chats.
How Chat Locking Works
Using the feature is designed to be simple and fast. To lock a chat, you can long-press or swipe on a conversation in your history, tap the Lock option, and confirm with your biometric or passcode.
To read a locked chat later, just tap into the Private locked folder and authenticate again. You can unlock a conversation at any time by repeating the same steps and selecting Unlock.
OpenAI says locked chats remain tied to your account and are still available across devices where Chat Lock is supported, but they will continue to require authentication each time you want to view them. The company also notes that notifications and previews for locked chats are hidden to prevent spoilers or leaks on your lock screen.
Ideal for Personal Discussions and Surprise Planning
OpenAI is positioning Chat Lock as the perfect solution for personal, sensitive, and just-for-you conversations.
That includes everything from relationship advice, health and financial questions, therapy-style journaling, and career planning, to more lighthearted uses like planning a surprise birthday party, proposal, holiday gift, or trip without a snooping partner, friend, or kid ruining it.
For many users, ChatGPT has become a confidant and brainstorming partner. Chat Lock acknowledges that reality, letting you be more open and honest in your prompts without worrying about who might pick up your phone next.
What It Means for Privacy on Shared Devices
The biggest impact is for shared devices and everyday phone-sharing moments.
Whether you regularly hand your phone to family members, let kids play games on it, share a tablet at home, or just have friends glance over your screen, Chat Lock adds a critical layer of separation between casual chats and private ones.
It doesn't replace full account security, like strong passwords, two-factor authentication, and logging out on public computers, but it solves a very common privacy gap: the unlocked, in-hand device.
Privacy advocates have long asked AI assistants to offer more granular controls beyond deleting history or using Temporary Chats. Chat Lock fills that middle ground — you keep your personal chats saved and useful, but hidden unless it's really you.
Availability and What's Next
OpenAI confirms Chat Lock is rolling out now to ChatGPT users on iOS and Android, with availability expanding over the coming weeks. Users will need the latest version of the ChatGPT app to see the option.
The company has not yet detailed when Chat Lock will come to the web version or desktop apps, but expanded support is expected as the rollout continues.
Chat Lock arrives alongside other recent privacy and personalization updates, including improved data controls, custom instructions, and memory management. Together, they signal OpenAI's broader strategy: make ChatGPT feel more personal, while giving users clearer tools to protect that personal information.
