ChatGPT Locked Chats Hide Logs Behind PINs, but Data Lingers
OpenAI has rolled out a Locked Chats feature for ChatGPT, letting users stash individual conversations behind a four-digit PIN or biometrics. While it keeps prying eyes away from your unlocked phone, account-level memory and stale browser sessions mean it offers far less privacy than it implies.
How ChatGPT Locked Chats actually works
The feature creates a dedicated, protected project folder inside your account to isolate sensitive conversations.
Setting it up takes a couple of clicks: open the three-dot menu in any chat window, select Lock Chat, and assign a four-digit PIN or link the prompt to your device's biometric authentication. Once enabled, the thread vanishes from your default chat sidebar and will not appear in local search queries until you authenticate.
Behind the scenes, ChatGPT aggregates these hidden sessions into a standalone Project space. It is designed around a very relatable scenario: handing your unlocked phone to a partner or colleague without exposing surprise party plans, medical questions, or financial drafting.
There is a sharp catch if you are forgetful. If you lose your PIN, OpenAI offers no backdoor recovery. Resetting the PIN triggers an immediate, permanent purge of every locked conversation and attached document tied to that PIN.
ChatGPT Locked Chats: specs and authentication requirements
| Spec | Detail |
|---|---|
| Authentication | 4-digit PIN, Face ID, fingerprint |
| Storage destination | Dedicated isolated Project folder |
| PIN recovery | None (PIN reset permanently deletes data) |
| Search visibility | Hidden until authenticated |
The interface loopholes that leave text exposed
Surface-level locking only works if the app interface cooperates, and early behavior shows obvious friction points. Locking an active chat does not automatically flush the active browser tab; the entire conversation can remain visible on screen until you navigate away or manually refresh.
Synced hardware introduces similar lag. If ChatGPT is open on your laptop while you lock a chat on your phone, the desktop client may continue to display the title and conversation view until that client fetches fresh account state.
More fundamentally, hiding an interface panel does not alter OpenAI's backend handling. Information shared during locked chats still feeds the broader account profile unless you manually disable the chatbot's persistent memory. Those who need ironclad legal confidentiality should remember that courts rule ChatGPT logs lack legal privacy regardless of local authentication barriers.
Do not treat this as a privacy vault. A four-digit PIN prevents someone sitting next to you on the train from snooping, but it is purely a front-end curtain. If a prompt contains information you cannot afford OpenAI or an automated crawler to see, your only real safeguard is not sending it in the first place.
Availability and rollout details
OpenAI is deploying Locked Chats across the ChatGPT web portal and official mobile apps for iOS and Android. The feature is arriving as a standard account setting for both free and paid subscribers, including Plus and Team tiers, requiring no additional subscription charge.
Frequently asked questions
What happens if I forget my ChatGPT Locked Chats PIN?
You must reset the PIN, but doing so instantly and permanently wipes all locked conversations and stored files associated with it.
Does Locked Chats stop ChatGPT from remembering personal facts?
No. The PIN only hides the thread visually. Unless you turn off the chatbot's global memory, details shared inside locked chats can still persist.
