Very few of our activities on the Internet are, strictly speaking, private. Nearly everything we do is logged somewhere, and our instant messaging is no exception. This is where Off-the-Record (OTR) Messaging can help. For those who are chatting about confidential matters (e.g., medical histories) or those who simply want their privacy, OTR can help keep instant messaging secure. OTR uses standard and well-tested cryptographic algorithms to keep our conversations confidential and prevent impersonation of our correspondents (e.g., in the event of account hijacking). In fact, many messengers, including the popular Adium for Mac and IM+ for Android devices already have OTR built-in. On Windows, OTR can be added to the popular Pidgin messenger by using the "Primary download" link on the OTR homepage, then going to Tools > Plugins and activating the Off-the-Record Messaging plugin.
