The message "User's security code has changed" in WhatsApp is a critical notification that indicates a significant change in the user's security settings. This message typically appears when the security code, which is used to verify the identity of users during conversations, has been altered.

Upon receiving this notification, users should take immediate action to ensure their account remains secure. Here are the steps they can follow:
- Verify Security Code: Compare the new security code with a trusted contact to confirm that it matches. This is a reliable way to verify that the change was legitimate and not the result of unauthorized access.
- Check Recent Activities: Review recent activities on your WhatsApp account, such as changes in phone number or device usage, to identify any unusual behavior.
- Contact Support: If there is any suspicion of unauthorized activity, users should contact WhatsApp support for further assistance and guidance on securing their account.
