End-to-end encryption

End-to-end encryption

Privacy and security is in our DNA, which is why we have end-to-end encryption. When end-to-end encrypted, your messages, photos, videos, voice messages, documents, status updates and calls are secured from falling into the wrong hands.

WhatsApp end-to-end encryption ensures only you and the person you're communicating with can read what's sent, and nobody in between, not even WhatsApp. Your messages are secured with locks, and only the recipient and you have the special keys needed to unlock and read your messages. For added protection, every message you send has an 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.

Important: End-to-end encryption is always activated. There's no way to turn off end-to-end encryption.

What's the "Verify Security Code" screen in the contact info screen?

Each of your chats has its own security code used to verify that your calls and the messages you send to that chat are end-to-end encrypted.

Note: The verification process is optional and used only to confirm that the messages you send are end-to-end encrypted.

This code can be found in the contact info screen, both as a QR code and a 60-digit number. These codes are unique to each chat and can be compared between people in each chat to verify that the messages you send to the chat are end-to-end encrypted. Security codes are just visible versions of the special key shared between you - and don't worry, it's not the actual key itself, that's always kept secret.

To verify that a chat is end-to-end encrypted

1. Open the chat.
2. Tap on the name of the contact to open the contact info screen.
3. Tap Encryption to view the QR code and 60-digit number.

If you and your contact are physically next to each other, one of you can scan the other's QR code or visually compare the 60-digit number. If you scan the QR code, and the code is indeed the same, a green check mark will appear. Since they match, you can be sure no one is intercepting your messages or calls.

If the codes don't match, it's likely you're scanning the code of a different contact, or a different phone number. If your contact has recently reinstalled WhatsApp or changed phones, we recommend you refresh the code by sending them a new message and then scanning the code.
