Here's how to share a ChatGPT conversation with a link, and how to take the link back. First, check the chat for private details. Anyone with the link can view it.
OpenAI says not to share health information, financial details, passwords or account numbers. Open the conversation and select Share. Look over the whole preview before you send anything.
Links are anonymous by default, but some older sharing screens can show your name. Select Create link or Copy link, whichever ChatGPT shows. Then send it.
A new link can take a moment to work. The link shows the chat as it was when you made it. New messages aren't added on their own.
To refresh it, select Share, then Update link. To remove links, open Settings, then Data controls. Next to Shared links, select Manage.
Delete one link, or open More actions to delete them all. Share the link. Delete it to stop access.
