In order to secure users’ chats, WhatsApp claims to use a unique security code which is used to verify that the calls and messages users send to that chat are end-to-end encrypted. These security codes are described as visible forms of special keys. Moreover, the contact information of the WhatsApp users display the code as a 60-digit number and a QR code.
Sometimes, the security codes can change due to reinstalling WhatsApp, switiching phones or removing a paired device. Notably, users can enable their security notifications to get alerts whenever the security code a contact’s device changes. Here are the steps for iOS, desktop and Android to enable these security code alerts.
