Just over a week ago, we announced that Iranian censors had started blocking all Signal traffic in the country. As an interim solution to help people in Iran get connected again, we’ve added support in Signal for a simple TLS proxy that is easy to set up, can be used to bypass the network block, and will securely route traffic to the Signal service. This new connection method is supported in the l

At Open Whisper Systems, our goal is to make private communication simple. A year ago, we announced a partnership with WhatsApp and committed to integrating the Signal Protocol into their product, moving towards full end-to-end encryption for all of their users by default. Over the past year, we’ve been progressively rolling out Signal Protocol support for all WhatsApp communication across all Wha

Signal Desktop now includes support for a new “Screen security” setting that is designed to help prevent your own computer from capturing screenshots of your Signal chats on Windows. This setting is automatically enabled by default in Signal Desktop on Windows 11.

Companies like Facebook aren’t building technology for you, they’re building technology for your data. They collect everything they can from FB, Instagram, and WhatsApp in order to sell visibility into people and their lives. This isn’t exactly a secret, but the full picture is hazy to most – dimly concealed within complex, opaquely-rendered systems and fine print designed to be scrolled past. The

The latest releases of Signal for Android, Desktop, and iOS are rolling out now with the ability to send optional link previews.

The latest Signal release includes some changes to the way safety numbers work. Safety numbers allow Signal users to verify the privacy of their communication with a contact, either by comparing a number or by scanning a single QR code. We recently introduced this new design as an update to Signal’s previous UX, which we felt was no longer adequate for what people had come to expect from Signal. L

Signal is the world’s most widely used truly private messaging app, and our cryptographic technologies provide extra layers of privacy beyond the Signal app itself. Since launching in 2013, the Signal Protocol—our end-to-end encryption technology—has become the de facto standard for private communication, protecting the contents of billions of conversations in WhatsApp, Google Messages, and many o

It’s a new year, and I’ve decided it’s a good time to replace myself as the CEO of Signal. I have now been working on Signal for almost a decade. It has always been my goal for Signal to grow and sustain beyond my involvement, but four years ago that would still not have been possible. I was writing all the Android code, was writing all of the server code, was the only person on call for the servi

As the world stands today, the future of transaction privacy does not look great.
