What is the "Verify security code" screen in my contact info/group info ?
This verification process is optional and is used only to confirm that the messages you send are end-to-end encrypted or not.
This code can be found in the contact info/group 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 ?
- Open the chat.
- Tap on the name of the contact or group to open the contact info/group info screen.
- 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 checkmark will appear. Since they match, you can be sure no one is intercepting your messages or calls.
If the codes do not match, it's likely you're scanning the code of a different contact, or a different phone number.
