Signal has become the privacy-focused consumer’s go-to messaging app. But a recent change to its back-end systems that was designed to make the app more accessible and competitive with other encrypted messaging services could be putting user data at risk.
At the core of Signal’s appeal is a level of digital protection and commercial disinterest in its users’ communications rarely seen by messaging service providers. Signal is now used broadly not just by hackers and professional paranoids, but activists, journalists, politicians, and any number of people who believe that their text messages and phone calls should be as private as an in-person conversation. Few other apps offer a similar level of security and privacy.
