How does WhatsApp ensure the security and privacy of user communications?

WhatsApp employs end-to-end encryption, meaning only the sender and recipient can read the messages, ensuring they're not accessible to WhatsApp or any third parties. Additionally, WhatsApp regularly updates its security measures, such as two-step verification, to safeguard user accounts from unauthorized access. These efforts underscore WhatsApp's commitment to maintaining the security and privacy of user communications.
