End-to-end encryption
End-to-end encryption Our DNA includes privacy and security, which is
why we have end-to-end encryption. End-to-end authentication guarantees
that your emails, images, videos, voice messages, files, status updates
and calls fall into the wrong hands.Buy VPN
End-to-end authentication from WhatsApp means that only you and the
person you communicate with can read what’s being sent, and no one in
between, not even WhatsApp.
Your messages are encrypted and you only
have the sender and the special keys you need to open your messages and
read them. Every message you send has a unique lock and key for added
protection. All this happens automatically: you don’t have to activate
settings or set up special secret chats to secure your messages.
Important: End-to-end encryption is disabled at all times. There’s no
way end-to-end authentication can be switched off.
In the contact info screen, what is the “Verify Security Code” screen?
That chat has its own security code to check that the end-to-end
encryption of your calls and messages you send to that chat.
Note: The verification process is optional and is only used to validate
the end-to-end encryption of the messages you send.
This code can be used as a QR code as well as a 60-digit number in the
contact info tab. These codes are unique to each chat and can be
compared in each chat to verify the end-to-end encryption of the
messages you send to the chat. Security keys are only readable versions
of the shared special key between you-and don’t worry, it’s not the
actual key itself, it’s always kept secret.
1.Open the chat to verify that a chat is encrypted end-to-end.
2.Tap the user name to open the contact information window.
3.Tap Show QR code authentication and 60-digit count.
If you are physically next to each other with your contact, one of you
can scan the QR code of the other or compare the 60-digit number
visually. If you scan the QR code and the code is actually the same, you
will see a green check mark. Because they suit, you can be certain that
your emails or calls are not detected by anyone.
If the codes don’t match, you’re probably scanning another contact’s
code, or another phone number. If you have recently reinstalled WhatsApp
or switched phones from your contact, we suggest that you refresh the
password by sending them a new message and then scanning the code.

If you are not physically close to each other and your touch, you can
give them the 60-digit number.
Let your contact know that when they
receive your code, they should write it down and then compare it
visually to the 60-digit number that appears under Encryption in the
contact info screen. You can use the Share button on the Verify Security
Code screen to send the 60-digit number via SMS, email, etc. for
Android, iPhone, and Windows Phone.
Are my end-to-end business messages and calls encrypted?
With end-to-end encryption, all WhatsApp messages and calls are secured.
However, it is important to remember that when you contact a business,
you may see your messages from several people in that business. A
company may employ another company to manage its communications, such as
storing, reading or responding to your messages.
The company with which you interact has a responsibility to ensure that
your communications are treated in compliance with your privacy policy.
Please contact the company directly for more information. Learn more
about end-to-end authentication for business messages in this post.
Why is WhatsApp offering end-to-end encryption and what does it mean to
keep people safe?
Security is critical to WhatsApp’s service. In 2016, we completed
implementing end-to-end encryption for all messaging and calling on
WhatsApp to ensure that no one, not even us, has access to your
conversation content. Digital safety has become even more important
since then. We have seen several examples of criminal hackers illegally
obtaining vast amounts of private data and abused technology to hurt
people with their stolen information. We have also expanded end-to-end
authentication to these apps as we have added more features–such as
video calling and status.
WhatsApp does not have the ability to view messages content or listen to
WhatsApp calls. That’s because messages sent on WhatsApp are encrypted
and decrypted entirely on your device. It is secured with a
cryptographic lock before a message ever leaves your device, and only
the receiver has the keys. Moreover, with every single message sent, the
keys change. While all this occurs behind the scenes, by checking the
security verification code on your phone, you can ensure that your
conversations are secure. Further info on how this works can be found in
our white paper.
Of course, people have been wondering what end-to-end encryption means
for law enforcement work. WhatsApp appreciates the work being done by
law enforcement agencies to ensure that people around the world are
safe. We carefully review, verify and respond to requests for law
enforcement based on relevant law and policy, and prioritize response to
requests for emergencies. We published information for law enforcement
about the limited information we receive and how they can make WhatsApp
requests that you can read here as part of our educational efforts.
