![]() Signal is in fact the messaging app of choice for many security and privacy concerned individual, the probably best known examples would be Edward Snowden, Jack Dorsey, and Bruce Schneier.Īt this point, I would be confident to say that Signal is the most secure messaging app that is easily available to the general public, the fact that there is a huge open source community reviewing the source code and identifying weaknesses ensures that. Might not be an issue for most people but still worth mentioning. You can only delete messages for everyone in a chat that have been sent no longer than 3 hours ago.Requires a mobile number for initial sign up.Available for iOS, Android, Mac, Windows, and Linux.Password protection (App will require PIN or password to open, good if your devices gets into the wrong hands).PIN Access ( you can set a PIN that is used to setup Signal on other/new devices).Open Source Signal protocol (used by other messaging apps as well).Option to send disappearing messages (with a timer). ![]()
