Today we’re making the Signal Desktop beta available. Signal Desktop brings the trusted private messaging experience of Signal to the desktop, with a simplicity that allows you to seamlessly continue conversations back and forth between your mobile device and your desktop computer.

Private messaging, now with all ten fingers

As always, everything is end-to-end encrypted and painstakingly engineered in order to keep your communication safe – allowing you to send high-quality private group, text, picture, and video messages for free.

Multiple devices, single identifier

Signal Desktop is a Chrome app which links with your phone, so all incoming and outgoing messages are displayed consistently on all your devices. Your contacts don’t have to guess where to message you, and when you switch devices the conversation you started will already be there.

Android devices only, for now

Update: Signal Desktop for iOS is here! Read more.

For the initial Signal desktop beta, only linking to Android devices is supported. Follow us on Twitter for updates on when the iOS app supports Signal Desktop.
