OpenAI\u2019s Locked chats feature<\/a> moves selected conversations out of your regular history and search and places them behind a four-digit account PIN or supported device authentication.<\/p>\n\n\n\n

The feature began rolling out on October 20, 2026, so it may not be available on your account yet. This guide shows you how to lock an existing chat, open and manage locked chats, change or reset your PIN, and understand what the feature does and does not protect.<\/p>\n\n\n\n

Quick Answer: How to Lock Chats in ChatGPT<\/strong><\/h2>\n\n\n\n

Open the conversation, select the three-dot menu (\u2022\u2022\u2022), and choose Lock chat<\/strong>. Confirm the action, then create your four-digit account PIN if prompted. To find it later, go to Projects > Locked chats<\/strong>. The exact steps can vary by platform and account, so check the options on your screen if they differ.<\/p>\n\n\n\n

What Are Locked Chats in ChatGPT?<\/strong><\/h2>\n\n\n\n

Locked chats are conversations you keep in your account but hide from everyday view. Once you lock a chat, it leaves your regular chat history, your pinned chats, and ChatGPT\u2019s<\/a> conversation search. It sits in a separate Locked chats area under Projects.<\/p>\n\n\n\n

Opening that area requires your 4-digit account PIN or supported device authentication. Locked chats do not appear in regular search results, so someone browsing your sidebar or searching your history will not find them.<\/p>\n\n\n\n

The feature is designed for shared screens and shared devices. It adds a barrier between your private conversations and anyone who can see your ChatGPT interface. It is not a security vault, however. Locking a chat does not add end-to-end encryption, does not change how long OpenAI retains the chat, does not remove information ChatGPT already remembered from it, and does not change your \u201cImprove the model for everyone\u201d setting. Anyone who can open a locked chat can still read and copy its contents.<\/p>\n\n\n\n

How to Lock Chats in ChatGPT: Step-by-Step Guide<\/strong><\/h2>\n\n\n\n

Step 1: Open the Conversation You Want to Protect<\/strong><\/h3>\n\n\n\n

Open the conversation in ChatGPT. Before you lock it, confirm you are signed into the correct account, since locking applies to the chat within that account. Locking works on existing saved chats, so start a conversation if you have not already done so.<\/p>\n\n\n\n

Step 2: Open the Three-Dot Menu<\/strong><\/h3>\n\n\n\n

Next to the conversation, select the more options menu, shown as three dots (\u2022\u2022\u2022). This menu holds the controls for the chat, including the lock option.<\/p>\n\n\n\n

Step 3: Select Lock Chat<\/strong><\/h3>\n\n\n\n

Choose Lock chat<\/strong> from the menu. ChatGPT asks you to confirm, so select Lock chat<\/strong> again to continue. Confirming moves the conversation into your locked chats.<\/p>\n\n\n\n

Step 4: Create or Enter Your Account PIN<\/strong><\/h3>\n\n\n\n

The first time you lock a chat or open the locked chats area, ChatGPT asks you to create a four-digit account PIN. Enter the PIN twice to confirm it. After that, you will enter the same PIN whenever you open locked chats. On supported mobile devices, you can also use Face ID, Touch ID, or your device unlock method in place of the PIN.<\/p>\n\n\n\n

Choose a PIN that others cannot easily guess. A four-digit code has only 10,000 possible combinations, so avoid birthdays, repeating digits, and common sequences such as 1234.<\/p>\n\n\n\n

Step 5: Verify That the Chat Is Locked<\/strong><\/h3>\n\n\n\n

After you lock the chat, it should disappear from your regular history, pinned chats, and search results. Open Projects > Locked chats<\/strong> to confirm it is there.<\/p>\n\n\n\n

Two details can cause confusion. First, the sidebar may show a Locked chats project while the titles of individual chats stay hidden until you authenticate. Second, search results and other signed-in devices may take time to refresh. A chat can also stay visible in the browser tab where you locked it, and content already loaded on other devices can remain on screen until those devices refresh. Close those tabs or refresh the app before you share your screen.<\/p>\n\n\n\n

How to Access and Open Locked Chats in ChatGPT<\/strong><\/h2>\n\n\n\n

To open a locked chat, follow these steps:<\/p>\n\n\n\n

    \n
  1. Open the Projects<\/strong> section in the sidebar.<\/li>\n\n\n\n
  2. Select Locked chats<\/strong>.<\/li>\n\n\n\n
  3. Enter your four-digit account PIN, or use supported device authentication.<\/li>\n\n\n\n
  4. Select the conversation you want to read.<\/li>\n<\/ol>\n\n\n\n

    Opening a locked chat gives you temporary access. It does not unlock the chat permanently or return it to your regular history. After you authenticate, chat titles may appear under Locked chats in the sidebar, so close the chat and leave the area when you finish.<\/p>\n\n\n\n

    How to Lock ChatGPT Chats on Mobile<\/strong><\/h2>\n\n\n\n

    Locked chats are available in the ChatGPT iOS and Android apps. Locking and opening work the same way as on the web: open the chat\u2019s three-dot menu, select Lock chat<\/strong>, and confirm.<\/p>\n\n\n\n

    On iPhone and iPad<\/strong><\/h3>\n\n\n\n

    On supported iPhones and iPads, you can open locked chats with your account PIN or with Face ID or Touch ID. Biometric unlock must be available on your device and turned on in ChatGPT\u2019s account PIN settings. If you do not see the option, use your PIN.<\/p>\n\n\n\n

    On Android<\/strong><\/h3>\n\n\n\n

    On Android, you can open locked chats with your account PIN or with your device unlock method, where it is supported. Look for the device unlock option in your PIN settings. It may not appear on every Android device or app version.<\/p>\n\n\n\n

    Device authentication is optional. It is set up separately on each device and does not replace your account PIN. If you use a new phone or reinstall the app, you may need to enter your PIN to restore access.<\/p>\n\n\n\n

    How to Change or Reset Your ChatGPT Locked Chats PIN<\/strong><\/h2>\n\n\n\n

    Changing your PIN and resetting a forgotten PIN are very different actions, so read this section carefully before you do either.<\/p>\n\n\n\n

    Change Your PIN Without Deleting Chats<\/strong><\/h3>\n\n\n\n

    If you know your current PIN and want a new one, open your account settings in ChatGPT and find the account PIN option. Enter your current PIN, then enter and confirm the new four-digit PIN. Changing the PIN does not delete your locked chats.<\/p>\n\n\n\n

    Menu names can vary by platform, so if you cannot find the option, check your settings under security or account protection.<\/p>\n\n\n\n

    What Happens If You Forget Your PIN?<\/strong><\/h3>\n\n\n\n

    Resetting a forgotten PIN permanently deletes all of your locked chats. It also deletes any information ChatGPT remembered only within those locked chats, along with files and other content protected only by the previous PIN. This cannot be undone, and OpenAI cannot recover that content.<\/p>\n\n\n\n

    Before you reset, check whether you have another copy of anything important. Locked chats are not a backup. If you cannot remember your PIN, do not treat a reset as a routine fix. It is the only way back into the account\u2019s locked chats, and it permanently removes everything stored there.<\/p>\n\n\n\n

    How to Permanently Unlock or Delete a Locked Chat<\/strong><\/h2>\n\n\n\n

    Permanently Unlock a Chat<\/strong><\/h3>\n\n\n\n

    To return a locked chat to your regular history, open it, select the three-dot menu, and look for the unlock option. Labels can differ between web, desktop, and mobile, so choose the option that describes returning the chat to regular history. Confirm when prompted.<\/p>\n\n\n\n

    Once unlocked, the chat appears in your regular history again and becomes visible to anyone using your ChatGPT account. Remember that unlocking changes visibility only. It does not change the chat\u2019s contents or the information ChatGPT has remembered from it.<\/p>\n\n\n\n

    Delete a Locked Chat<\/strong><\/h3>\n\n\n\n

    To delete a locked chat, open it, select the three-dot menu, and choose delete. Confirm the deletion. Deleted chats cannot be recovered, so be sure you no longer need the conversation before you delete it.<\/p>\n\n\n\n

    What Does ChatGPT\u2019s Locked Chats Feature Actually Protect?<\/strong><\/h2>\n\n\n\n

    Locked chats hide conversations from everyday view, but they are not a complete privacy solution. This table summarizes what the feature does and does not change.<\/p>\n\n\n\n

    Privacy aspect<\/strong><\/td>What users should know<\/strong><\/td><\/tr>
    Regular chat history<\/td>Locked conversations are hidden from regular history and pinned chats.<\/td><\/tr>
    Conversation search<\/td>Locked chats do not appear in regular conversation search.<\/td><\/tr>
    Access protection<\/td>Opening locked chats requires your account PIN or supported device authentication.<\/td><\/tr>
    Encryption<\/td>Locking does not create end-to-end encryption or a separate encrypted vault.<\/td><\/tr>
    Existing memories<\/td>Information ChatGPT already remembered is not removed when you lock a chat.<\/td><\/tr>

    Copying content<\/td>Anyone who can open a locked chat can still copy its contents.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Locked chats also cannot be archived, pinned, moved, or shared while they are locked. Files uploaded or created in a chat are protected when you lock the chat. Files that were added to the chat from outside it keep their original access rules, so review them separately if they are sensitive.<\/p>\n\n\n\n

    ChatGPT Temporary Chat vs. Locked Chats<\/strong><\/h2>\n\n\n\n

    Temporary Chat and Locked chats both keep conversations out of your regular history, but they serve different purposes.<\/p>\n\n\n\n

    Feature<\/strong><\/td>Locked chats<\/strong><\/td>Temporary Chat<\/strong><\/td><\/tr>
    Purpose<\/td>Keep a conversation and restrict access to it<\/td>Start a conversation that does not stay in regular history<\/td><\/tr>
    Access protection<\/td>Requires account PIN or supported device authentication<\/td>No separate PIN protection<\/td><\/tr>
    History visibility<\/td>Hidden from regular history and search, stored in Projects > Locked chats<\/td>Does not appear in chat history<\/td><\/tr>
    Memory behavior<\/td>Has its own memory section, separate from regular chats<\/td>Does not create or update memories<\/td><\/tr>
    Returning later<\/td>You can return to the chat at any time<\/td>The conversation is not kept in your history for later return<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Choose Locked chats when you want to keep a conversation you may need again and limit who can open it. Choose Temporary Chat when you want a conversation that is not saved in your history. For the latest details on how Temporary Chat handles data, see OpenAI\u2019s Temporary Chat documentation.<\/p>\n\n\n\n

    Why Can\u2019t I See the Lock Chat Option?<\/strong><\/h2>\n\n\n\n

    If the option is missing, work through these checks:<\/p>\n\n\n\n

      \n
    • The feature has not reached your account yet.<\/strong> Locked chats are rolling out gradually, so availability can differ between accounts even on the same plan.<\/li>\n\n\n\n
    • Your plan or platform may not be included yet.<\/strong> The initial rollout covers consumer plans on the web, the iOS and Android apps, and the new ChatGPT desktop app for macOS and Windows. Check the release notes for the current list.<\/li>\n\n\n\n
    • The conversation type may be unsupported.<\/strong> OpenAI\u2019s Help Center lists conversation types that cannot be locked, so check that article if your chat is one of them.<\/li>\n\n\n\n
    • The interface has not refreshed.<\/strong> Close and reopen the app or refresh the browser page, then check the three-dot menu again.<\/li>\n<\/ul>\n\n\n\n

      Updating the app, changing settings, or upgrading a subscription may not make the feature appear. If the option is still missing after the rollout reaches your account, contact OpenAI Support.<\/p>\n\n\n\n

      Should You Use the LockGPT Chrome Extension?<\/strong><\/h2>\n\n\n\n

      Third-party browser extensions also offer chat locking. One example is LockGPT, which is listed in the Chrome Web Store. Its listing describes PIN protection and chat hiding, and says it encrypts chats locally in your browser. These are the developer\u2019s claims. I did not find independent verification of its encryption or security.<\/p>\n\n\n\n

      Before installing any extension that works with ChatGPT, review the publisher information, the permissions the extension requests, its privacy policy, and recent user reviews. A third-party security scanner rated LockGPT\u2019s requested permissions as medium risk, and at the time of the most recent snapshot I could find, the listing had roughly 168 users and a single public review. Those numbers are small and may have changed since, so check the listing yourself.<\/p>\n\n\n\n

      The extension\u2019s privacy policy states that it does not collect personally identifiable or financial information, that it stores a PIN you set, and that its locking operations happen in your browser. Those statements are the developer\u2019s, and a browser extension that can read or modify pages on chatgpt.com has access to the content of the pages you open. If you use an extension, you are trusting its code and the company behind it.<\/p>\n\n\n\n

      For most users, OpenAI\u2019s built-in feature is the better first choice, because it is part of ChatGPT itself and does not require granting a third-party extension access to your browser. Use an extension only if the built-in option is not available to you and you have reviewed its permissions and policies.<\/p>\n\n\n\n

      Best Practices for ChatGPT Conversation Security<\/strong><\/h2>\n\n\n\n
        \n
      • Use a PIN that others cannot guess.<\/strong> Avoid birthdays, repeated digits, and simple sequences.<\/li>\n\n\n\n
      • Protect your account credentials.<\/strong> Anyone who knows your ChatGPT login may be able to access your account.<\/li>\n\n\n\n
      • Lock chats after you view them.<\/strong> Make it a habit to lock sensitive chats once you finish with them.<\/li>\n\n\n\n
      • Check other open devices and tabs before sharing your screen.<\/strong> Locked chats can remain visible in an open window.<\/li>\n\n\n\n
      • Review shared links separately.<\/strong> Locking a chat does not replace managing the links you have created.<\/li>\n\n\n\n
      • Understand memory and workspace policies.<\/strong> Locking does not remove information ChatGPT has already remembered, and an organization may apply its own retention rules.<\/li>\n\n\n\n
      • Do not reset a forgotten PIN casually.<\/strong> A reset permanently deletes everything protected by that PIN.<\/li>\n<\/ul>\n\n\n\n

        Final Verdict<\/strong><\/h2>\n\n\n\n

        Locked chats are a useful way to keep selected conversations out of your regular ChatGPT history and search, especially on shared screens and devices. They are not encryption, and they do not change retention, memory that was already saved, or your model-improvement settings. Before you rely on the feature, understand how the PIN works, what a forgotten-PIN reset deletes, how shared links behave, and whether your workspace policies apply.<\/p>\n\n\n\n

        Your next step is simple. Open a conversation you want to keep private, select the three-dot menu, and choose Lock chat<\/strong>. If the option is not there yet, check back as the rollout reaches your account.<\/p>\n\n\n\n

        Frequently Asked Questions<\/strong><\/h2>\n\n\n\n

        Can you password-protect individual chats in ChatGPT?<\/strong><\/h3>\n\n\n\n

        Yes, with OpenAI\u2019s Locked chats feature, which uses your four-digit account PIN or supported device authentication. The feature is rolling out gradually, so check whether it is available on your account.<\/p>\n\n\n\n

        Where do locked chats go in ChatGPT?<\/strong><\/h3>\n\n\n\n

        They move out of your regular history, pinned chats, and search results. You can find them under Projects, then Locked chats. Titles may stay hidden until you authenticate.<\/p>\n\n\n\n

        Can someone see my locked chats if they open ChatGPT?<\/strong><\/h3>\n\n\n\n

        They should not be able to see locked chat titles or contents without your PIN or device authentication. Anyone who knows your PIN, or who can use your unlocked device, may still open them.<\/p>\n\n\n\n

        Can I lock ChatGPT chats on my phone?<\/strong><\/h3>\n\n\n\n

        Yes, in the supported iOS and Android apps. Use the three-dot menu on the chat and select Lock chat. On supported devices, you can open locked chats with Face ID, Touch ID, or device unlock.<\/p>\n\n\n\n

        What happens if I forget my ChatGPT PIN?<\/strong><\/h3>\n\n\n\n

        Resetting the PIN permanently deletes all locked chats, along with information and files protected only by that PIN. This cannot be undone, and OpenAI Support cannot recover the deleted content.<\/p>\n\n\n\n

        Does locking a chat delete it?<\/strong><\/h3>\n\n\n\n

        No. The chat stays in your account and moves to Locked chats. Only deleting the chat removes it.<\/p>\n\n\n\n

        Can I search for a locked ChatGPT conversation?<\/strong><\/h3>\n\n\n\n

        Not with regular chat search. Locked chats do not appear in regular search results. Open Projects, then Locked chats, and authenticate to find them.<\/p>\n\n\n\n

        Does locking a chat stop ChatGPT from remembering what I said?<\/strong><\/h3>\n\n\n\n

        No. Locking does not remove information ChatGPT has already remembered from that chat. Locked chats have their own memory section, and new memories from them are not used in regular chats, but the feature does not change what has already been saved. Review your memory settings if you want to control what ChatGPT remembers.<\/p>\n","protected":false},"excerpt":{"rendered":"
