On the surface, it might seem like your personal texts and instant messages are private, but that’s far from the truth. When you don’t encrypt your messages, the companies who create the apps and third parties like government officials can read your private messages.

Encrypted messaging apps like WhatsApp make it difficult for anyone else to eavesdrop on your conversations. While VPNs do a great job hiding your IP address, even the best VPNs won’t help if you’re using a messaging app that stores identifiable metadata on its server. They do, however, cover any gaps where messaging apps don’t encrypt. Keep reading to learn more about how encrypted messaging works and our top messaging apps for security and privacy. 

How Encrypted Messaging Works

Encrypted messaging is implemented by what’s known as end-to-end encryption (E2EE). End-to-end encryption occurs at the device level. It only allows the sender and receiver of a specific conversation to read the messages they send to each other. In other words, no third parties will be able to pick up any of the messages you send or receive. Encrypted messaging also helps with blocking hackers and potential cyber-attacks
