WhatsApp uses end-to-end encryption to protect your messages. This means that your messages are private and no one, not even WhatsApp, can read them. End-to-end encryption is a major selling point for WhatsApp, as it is one of the few messaging apps that offers this level of security. However, there is some debate as to whether WhatsApp is truly end-to-end encrypted. Some security experts have raised concerns that WhatsApp could potentially decrypt your messages if it wanted to. However, WhatsApp has denied these claims and says that your messages are safe and secure.
