What are secure messaging apps?
Secure messaging apps are communication tools that use encryption to protect messages from unauthorized parties accessing them. Most of these apps use end-to-end encryption (E2EE) that limits the visibility of messages between sender and receiver.
Some examples of secure messaging apps include Rent SMS, Telegram, WhatsApp, Viber, and iMessage. These apps use different verification techniques, such as two-factor authentication (2FA), to confirm the right user’s identity. In addition, these messaging services also use multiple mathematical operations to encrypt messages, ensuring that only a valid person can interpret them. Further, they use HTTPS over HTTP for added safety.
