Do you trust that new chat locking features are enough to keep your personal data private?
OpenAI has introduced a new locking feature for ChatGPT that allows users to secure specific conversations behind a four-digit PIN, Face ID, or Touch ID. This security layer moves protected chats into a dedicated, isolated section separate from standard history and search results.
Why it matters
The update provides a mechanism for maintaining data privacy when a shared device is used, isolating sensitive history from the primary interface. It addresses the growing need for granular control over persistent AI logs in multi-user or device-sharing environments.
The system utilizes a four-digit PIN, Face ID, or Touch ID to gate access to protected conversations. Resetting this PIN triggers a total purge of all content previously secured under that credential.
The players
OpenAI
An AI research and deployment company known for the GPT series of large language models and the ChatGPT consumer interface.
The details
Once a user activates the lock, the specific conversation is migrated to a secure silo, removing it from general search results and standard session history. These locked threads maintain a unified, independent memory state that is shared only among conversations within that secured section. The architecture is designed to isolate these interactions from the primary history stream, though it remains unsupported for temporary, archived, shared, group, or scheduled chats, and meeting recordings.
Timeline
October 20, 2026: OpenAI announced and began the rollout of the locking feature.
The Tech Race
This move segments ChatGPT's previously monolithic history log into tiered access levels. It follows industry trends toward embedding granular security controls directly into consumer AI applications to match traditional data-protection standards.
The feature is rolling out to users on Free, Go, Plus, Pro, Business, Enterprise, and Edu plans, though it is currently unsupported on ChatGPT for Healthcare. Users can now isolate private sessions immediately upon the feature's arrival on their device.
The takeaway
This update allows users to protect sensitive logs from casual viewing on shared hardware. Watch for whether OpenAI expands this gating to include shared or group chats in future updates.
