Off-the-record chats are secure, private and disappear once ended.the-record (OTR) messaging
Off-the-record (OTR) Messaging is a feature that allows users to exchange temporary, encrypted messages directly with each other. This happens by using the local**,** non-persistent session storage of their browser rather than storing messages on the Rocket.Chat server. After an OTR session ends and the session storage is cleared, the OTR messages are removed and can no longer be restored.
As an administrator, you can enable/disable OTR for your workspace, as shown below:
Go to Administration > Workspace > Settings > OTR.
