Hi OpenAI team!
I’d really love a chat lock feature — something like a PIN, password, or even Face ID — to protect important or private chats in ChatGPT.
I’m 10 years old and use ChatGPT for learning, vocab practice, stories, and more. But I share my account with family, and sometimes chats get deleted or changed by accident.
It would be amazing to have a way to “lock” certain chats:
• So they can’t be deleted or edited unless unlocked
• So others can’t see private chats
• Maybe even have a little lock icon 
or a way to hide them!
I saw others asking for this too, so I hope it becomes a real feature. Thank you for making ChatGPT so useful and fun — it’s my favourite learning tool ever!
