Moreover, Signal helps you use an end-to-end encrypted connection to chat with your contacts, with the keys (also known as safety numbers) used to encrypt it being stored on the end devices and easily verifiable to instantly check and verify the identity of the person on the other end.

As a testimony to its efficiency, the Signal Protocol is used by some of the most popular messaging platforms out there at the moment, including WhatsApp and Facebook's Messenger, with a market of over one billion users.
