Without any fanfare, the Senate Sergeant at Arms recently told Senate staffers that Signal, widely considered by security researchers and experts to be the most secure encrypted messaging app, has been approved for use by all Senate staff members.
The news was revealed in a letter Tuesday by Sen. Ron Wyden (D-OR), a staunch privacy and encryption advocate, who recognized the effort to allow the encrypted messaging app as one of many “important defensive cybersecurity” measures introduced in the chamber.
I have written several times about Signal in past articles in this blog. See https://privacyblog.com/?s=Signal for those past articles.
As the Senate Sergeant at Arms recently stated, Signal is considered to be one of the most most secure encrypted messaging apps available today, perhaps even THE most secure encrypted messaging app available. Best of all is the price tag: FREE.
Signal is available for iPhone, iPad, Android devices, and also is available as a beta test product for the Chrome web browser running on desktop systems. See https://whispersystems.org/ for the details.
