What is Signal Messenger?
Signal is a cross-platform encrypted messaging app that prioritizes user privacy and security. It utilizes internet-based communication to enable one-on-one and group messaging, allowing the exchange of various content types including files, voice notes, images, and videos. Developed by the Signal Foundation and Signal Messenger LLC, this app sets itself apart by making privacy the default, rather than an optional feature. The encrypted nature of all communications, from individual messages to group conversations, is a core aspect of the Signal experience, ensuring the confidentiality of user interactions
