Privacy and Security is in our DNA
From day one, we built WhatsApp to help you stay in touch with friends, share vital information during natural disasters, reconnect with separated families, or seek a better life. Some of your most personal moments are shared with WhatsApp, which is why we built end-to-end encryption into the latest versions of our app. When end-to-end encrypted, your messages, photos, videos, voice messages, documents, and calls are secured from falling into the wrong hands.
Security by Default
WhatsApp's end-to-end encryption is available when you and the people you message use the latest versions of our app. Many messaging apps only encrypt messages between you and them, but WhatsApp's end-to-end encryption ensures only you and the person you're communicating with can read what is sent, and nobody in between, not even WhatsApp. This is because your messages are secured with a lock, and only the recipient and you have the special key needed to unlock and read them. For added protection, every message you send has its own unique lock and key. All of this happens automatically: no need to turn on settings or set up special secret chats to secure your messages.
