Windows Insiders and Skype insiders on other platforms can now use a new feature “Private Conversations” that brings end-to-end encrypted Skype audio calls and text messages or sending files like images, audio, and videos. Microsoft has today announced availability of this feature that will make using Skype more secure.

With Private Conversations, you can have end-to-end encrypted Skype audio calls and send text messages or files like images, audio, or videos, using the industry standard Signal Protocol by Open Whisper Systems. The content of these conversations will be hidden in the chat list as well as in notifications to keep the information you share private.

Private Conversations are available now to Skype Insiders using Skype version for iOS, Android, Linux, Mac, and Windows Desktop. During the preview, one will only be able to start private conversations with other Skype Insiders also running the latest preview version.

How to use private conversations:

Give it a try by selecting “New Private Conversation” from the compose menu or from the recipient’s profile. After the recipient accepts your invite, all calls and messages in that conversation will be encrypted end-to-end until you choose to end it. You can only participate in a private conversation from a single device at a time. You can switch the conversation to any of your devices, but the messages you send and receive will be tied to the device you’re using at the time.
