OpenAI is reportedly building a major new privacy feature for ChatGPT. It will let you lock individual conversations behind a PIN or fingerprint. The feature was found in an APK teardown of the latest ChatGPT Android build (version 1.2026.230) by Android Authority's Karandeep Singh Oberoi and AssembleDebug. It aims to give users more control over who can see their sensitive AI chats. The move could meet long-standing user requests for stronger privacy controls. It would offer a way to keep private talks with the AI safe but still saved. This guide covers ChatGPT could soon let you lock chats behind a PIN or fingerprint in detail. Here is everything you need to know about ChatGPT could soon let you lock chats behind a PIN or fingerprint, step by step.
ChatGPT could soon let you lock chats behind a PIN or fingerprint: How Will ChatGPT's Locked Chats Work?
The new 'locked chats' feature is meant to hide specific conversations from your regular sidebar, chat history, and search results. You can only open them after you enter a PIN or scan your fingerprint. This is very different from ChatGPT's existing 'Temporary Chats.' Temporary Chats keep things private by not saving them to your history at all, but you can't go back to them later. The code strings found in the Android app show that locked chats will stay locked even after you open them. You will need to take a clear step to turn them back into regular chats. This ongoing security measure is helpful for people who share devices and want to stop others from reading their private AI chats.

A key part of locked chats is how they work with ChatGPT's 'Memory' feature. Locked conversations can use information ChatGPT has learned from both regular and other locked chats. But any new memories made inside a locked chat will stay only inside other locked conversations. This creates a 'privacy boundary.' It makes sure sensitive information shared in a protected chat does not spill over into your regular, unlocked chats. This 'sandbox' approach for sensitive data is a smart design choice. It helps ease worries about data leaking across different chat contexts.

Why This Matters for ChatGPT Users and Data Privacy
The launch of locked chats is a big step forward for user privacy in ChatGPT. For years, users have had all kinds of talks with AI. Some were simple questions. Others were deeply personal or professional, about money, private projects, or even health. The default behavior of saving chat history is handy for keeping track of past talks. But it has always created a privacy problem, especially because OpenAI's CEO Sam Altman has warned that chats are not legally protected and can be subpoenaed. OpenAI does offer options like turning off data training and using Temporary Chats. But these often have trade-offs. For example, you may lose useful context or can't go back to past talks.
This new feature directly fixes the limits of Temporary Chats. Temporary Chats give you a clean slate and are not used for model training by default. But they are short-lived by nature. You can't save or revisit these private, one-time chats. That has been a major drawback for users who need both privacy and the ability to keep their history. Locked chats fill this gap. They let you keep a searchable, personal history of sensitive topics without exposing them to casual onlookers. They also help protect the integrity of your other chats. This goes beyond simply hiding chats, as the existing archive feature does, by adding a strong login step.
The development also fits with broader industry trends and user expectations for better digital privacy. In a time when data breaches and privacy worries are top of mind, and with laws like the EU AI Act setting stricter rules, AI platforms are under growing pressure to offer stronger data protection. OpenAI has already added features like 'Lockdown Mode' to guard against prompt injection attacks and data theft for high-risk users. It has also added 'Computer History' for macOS, though that feature raised concerns about unencrypted local memory files. Locked chats focus on conversation-level login. They offer a more direct and user-friendly solution for personal privacy within the app itself.
What This Means
For individual users, locked chats will offer peace of mind. You can talk with ChatGPT about highly sensitive subjects without fear of accidental exposure. Whether you are drafting a private email, brainstorming a personal project, or talking about your finances, the ability to lock these chats with a PIN or fingerprint means that even if a device is unlocked or an OpenAI session is left open, these specific chats stay protected. This builds more trust and encourages you to use the platform with confidence for a wider range of personal and professional tasks.
For OpenAI, this feature shows a strong focus on user privacy. It responds to direct and indirect feedback from its community. User requests for PIN protection for chat history and memory have shown up in developer forums. This proves a clear demand for such controls. By building this, OpenAI not only improves the security of ChatGPT but also sets it apart in a competitive market where AI privacy is a growing concern. The careful separation of memory from locked chats also shows OpenAI understands the complex privacy issues around AI personalization.
What's Next
The feature was spotted in an Android app teardown, which shows it is actively under development. But there is no official timeline for its public release. Still, the presence of fully written strings in the code suggests a launch may come soon. Users should expect an official announcement from OpenAI about the feature's availability across different platforms (web, iOS, and Android). The announcement will likely include clear instructions on how to turn on and manage locked chats. It will be important for OpenAI to provide good onboarding materials. These should explain the difference between locked chats and Temporary Chats, as well as how they handle memory. As AI becomes a bigger part of daily life, expect more new features in privacy and security. Companies will keep trying to balance powerful AI tools with strong user data protection.
