What is the security number?

Every Whatsapp chat is end-to-end encrypted and for this reason, is given a unique security number. In this way, it can be checked whether the end-to-end encryption is actually in place (the actual key naturally remains secret and has nothing to do with the number).

The security number is stored as a QR code or a 60-digit number in the contact information of the respective chat and can change under certain conditions or circumstances. This happens, for example, when …
