Edward Snowden has publicly endorsed the Signal app multiple times, often pointing to its strong security and privacy protections—especially its use of end-to-end encryption—and indicating that he personally relies on it for secure communication. Here are two key statements he has made about Signal based on publicly available information:
In November 2015, Snowden tweeted, “I use Signal every day. #notesforFBI (Spoiler: they already know),” highlighting his personal use of the app and its reputation for privacy, even suggesting that the FBI was aware of its security.
On January 7, 2021, in response to a user asking if Signal could be trusted, he replied, “Here’s a reason: I use it every day and I’m not dead yet.” This was during a surge in Signal’s popularity following WhatsApp’s privacy policy changes, underscoring his confidence in its safety.
His comments reflect both his personal reliance on the app—stemming from his need for secure communication as a whistleblower—and his broader advocacy for privacy tools, frequently positioning Signal as a leading option for secure messaging.
