THE ALTERNATE UNIVERSE OF MEREDITH WHITAKER

It's free. It doesn't track you or serve you ads. It pays its engineers very well. And it's a go-to app for hundreds of millions of people.

TEN YEARS AGO, WIRED PUBLISHED A news story about how two little-known, slightly ramshackle encryption apps called RedPhone and TextSecure were merging to form something called Signal. Since that July in 2014, Signal has transformed from a cypherpunk curiosity-created by an anarchist coder, run by a scrappy team working in a single room in San Francisco, spread word-of-mouth by hackers competing for paranoia points-into a full-blown, mainstream, encrypted communications phenomenon. Hundreds of millions of people have now downloaded Signal. (Including Drake: "Cuban girl, her family grind coffee," he rapped in his 2022 song "Major Distribution." "Text me on the Signal, don't call me.") Billions more use Signal's encryption protocols integrated into platforms like WhatsApp.
