Security Verification WhatsApp End-to-End Encryption.

WhatsApp has released an end-to-end encryption security feature, marking the biggest change in WhatsApp history. Now, all information sent via WhatsApp will be secured with 256-bit code encryption. This means that only you and your friend, to whom you are sending the message, can see the content. Third parties, including hackers, cybercriminals, government agencies, and even WhatsApp itself, will not have access to your messages, calls, videos, photos, documents, etc. However, to ensure this security, you need to check and verify your end-to-end encryption with your friends.

How to Check End-to-End Encryption Security in WhatsApp?

Open WhatsApp on your smartphone, Choose the friend’s contact or group with which you want to check encryption security.

When you will open the contact or group chat screen a message will appear on the chat screen with a lock icon. This message will be something like this.


“Messages you send to this chat and calls are now secured with end-to-end encryption. Tap for more info.”

When you tap on the message, you will get more information related to encryption:

“Messages you send to this chat and calls are now secured with end-to-end encryption. Which means WhatsApp and third parties can’t read or listen to them.”

If you see above message your connection is encrypted with your friend or with group chat. Sometimes if your friend has not updated their WhatsApp or he/she is using a different version of WhatsApp than yours. Then You will see the message in View contact/group info page, something like this:


“Messages you send to this chat and calls are not end-to-end encrypted. Tap for more info.”

And when you tap on the message then you will get correct information why the connection is not secure or not encrypted:

“Messages you send to this chat and calls are not end-to-end encrypted because your “friend” needs to update WhatsApp.”

And also when your friend Switches their mobile number or reinstall the WhatsApp then another message will appear on the chat screen:


“Your Friend’s security code changed, tap for more info.”

& When you tap on the message then you will get this info:

“Your Friend’s security code changed, likely because your friend reinstalled WhatsApp or switched phones tap “verify” to confirm new security.”

If you receive this message then you will need to verify end-to-end encryption security. So how to verify end to end encryption.

  • Next, you will get a QR code and a 60-digit number. The QR code and the 60-digit number are unique between you and your friend only.

  • Share the QR code and 60-digit number with your WhatsApp friend via WhatsApp, other instant messengers (e.g., Hike, WeChat, Facebook), and through Email-Gmail service.


  • After sending, instruct your friend to match the 60-digit number because it will be the same between you and your friend. Alternatively, they can scan the QR code using their WhatsApp QR code scanner.


Your friend can transfer the QR code image to their PC/Laptop or another smartphone and then scan it with their WhatsApp QR code scanner. After QR code verification, you can check your end-to-end encryption verification in the “View Contact/Group info” screen.

That’s it! Now you have successfully verified your end-to-end encryption with your friend.
