What is End-to-End Encryption in Whatsapp?

The latest version of WhatsApp includes the security feature known as End-to-End Encryption. As WhatsApp deals with people, the security level of the information shared is considered as a top priority when it comes to instant messenger services.

When encryption is active, it saves your messages, photos, videos, voice messages, documents, status updates, and calls details from being placed in wrong hands.

The end-to-end encryption is activated by default when both the sender and recipient has the latest version of WhatsApp installed.

This feature ensures that only the sender and the receiver can read the messages, watch the videos, listen to audio notes and view the picture sent. No one else. Not even WhatsApp can access it. The security system is designed in such a way that every chat and text contain a lock code and a key. The unique key to open the message is available only in the receiver’s device. All these are automatic and happens in no time.
