ChatGPT Now Lets You Lock Chats with a PIN

OpenAI has added a new 'Locked Chats' feature to ChatGPT that lets users secure conversations with a PIN. Specific chats can be locked and hidden using a four-digit PIN or fingerprint and facial recognition.

Locked chats are moved to a 'Projects > Locked Chats' section, where they no longer appear in the regular chat history or search results. The feature is useful for users who want to keep certain conversations hidden from others without deleting them.

The news was reported on November 2, 2026, by Kurt Knutsson's CyberGuy Report. With a growing number of users discussing sensitive topics such as personal advice and worries with AI, the feature was introduced as a privacy protection measure.
