Proton Mail launches the world’s first encrypted contacts manager

Starting today, the new contacts manager is available to all of Proton Mail’s five million users around the world.

The development and launch of this feature was driven by the feedback that the company received from many of its users in the investigative journalism space. “Last year, we had the unique opportunity to meet with many of our users in the field at the Second Asian Investigative Journalism Conference in Kathmandu, Nepal, and one message that we heard over and over again was the need for better ways to protect sources,” says Proton Mail co-founder Dr. Andy Yen, “the new encrypted contacts manager today is the result of over one year of research and development into how we can best meet the needs of the thousands of activists, journalists, and dissidents who rely on Proton Mail to protect their privacy.”

In addition to protecting sensitive contact details with zero-access encryption (meaning that Proton Mail itself cannot decrypt the data, and cannot reveal the private email contact details to third parties), Proton Mail’s new contact manager also utilizes digital signatures to verify the integrity of contacts data.

“Combining encryption with digital signatures provides powerful protection that guarantees not only the privacy, but also the authenticity of the contacts saved in Proton Mail, and reduces the need to trust Proton Mail, as even we cannot access or change this information without your knowledge,” says Dr. Yen. In line with standard company practice, the software behind Proton Mail’s encrypted contacts manager is fully open source.
