OpenAI's October 20, 2026 ChatGPT release notes announce a new feature called Locked Chats, designed to keep selected conversations out of the usual chat history, search results and pinned items. The update is a product-level privacy change rather than a development in search ranking or AI visibility.
The official source is the ChatGPT Release Notes. Users should consult the current in-product instructions for the exact setup and authentication options available to their account.
What are Locked Chats?
Locked Chats provide a way to protect selected conversations and make them less visible in the standard ChatGPT interface. According to the release-note description, locked conversations are hidden from the normal history, search and pinned items. The feature is intended for situations where a user wants an additional layer of privacy around particular conversations.
What the feature does—and does not—establish
Hiding a conversation from the usual interface is not the same as deleting it. Nor should users assume that the feature provides end-to-end encryption or changes all account-level data-retention settings. Those are separate technical and policy questions, and the release-note announcement alone does not establish such guarantees.
For the most accurate details about locking and unlocking chats, authentication requirements and availability, users should follow OpenAI's current product instructions and settings.
Does this affect SEO or AI Search?
No direct SEO impact has been established. The announcement does not describe changes to web crawling, indexing, search rankings, AI citations or referral traffic. It is primarily a ChatGPT privacy and interface update.
For publishers and SEO teams, the item is relevant only as part of broader coverage of changes to AI products and user controls. It should not be framed as a new AI Search visibility opportunity or as a change to how ChatGPT retrieves and cites public websites.
NetContentSEO assessment
Locked Chats is a concise product update worth documenting for readers who follow OpenAI's product changes. The useful editorial angle is to explain what is hidden from the standard interface while avoiding stronger claims about encryption, deletion or data retention that the announcement does not support.
