Your security code with the user has changed. What does WhatsApp mean - briefly?

Your security code with the user has changed. What does WhatsApp mean - in detail?
When you receive a notification from WhatsApp that "Your security code with [user] has changed," it means that the encryption key used to secure your communication with that specific contact has been updated. This change can occur for several reasons, including changes in the user's device or phone number, or simply due to routine updates by WhatsApp to enhance security measures.
WhatsApp uses end-to-end encryption to protect messages and calls between users. Each conversation is locked with a unique security code known only to the devices involved in the communication. If this code changes, it indicates that the encryption key has been refreshed, ensuring continued privacy and security for your conversations.
It's important to note that while this change does not necessarily indicate any malicious activity, it is always prudent to verify the security code with your contact to ensure that no unauthorized access has occurred. WhatsApp provides a simple way to compare security codes by scanning a QR code or manually entering the 60-digit number.
In summary, when WhatsApp notifies you of a change in your security code, it signifies an update in the encryption key used for secure communication with that contact. This routine process is part of WhatsApp's ongoing efforts to maintain robust security and privacy for its users.
