The Signal messenger is a popular and secure person to person internet messaging that is used for both web and phone-based applications communications globally. Signal has well known due to the privacy it provides along with several custom encryption techniques. This security feature helps in keeping a close eye on the chats ensuring the privacy of the user. Today, the end-to-end encrypted protocols have become the most important feature in any messaging application, and Signal is no other exception. The application uses this protocol and does not share its application’s data with any other existing app. The most important thing I would like to tell is that it is also supported by Linux platforms. These all features discussed make this application a top choice of today’s users.
