What does a Certificate Mismatch Warning indicate?

A Certificate Mismatch Warning indicates that there is a discrepancy between the URL that a user is trying to access and the security certificate that is being presented by the server. When a user connects to a website secured with HTTPS, the browser validates the website’s certificate to ensure that it authentically represents the domain to which the user is connecting. If the certificate does not match the URL, it raises a warning to alert the user that they may not be connecting to the intended site. This warning is crucial as it helps protect users from potential phishing attacks or other malicious activities that could occur if they were led to a fraudulent website masquerading as a legitimate one.

The other options do not accurately describe the specific nature of a Certificate Mismatch Warning. Invalid credentials relate to authentication issues rather than certificate validation, expired sessions do not directly pertain to certificate mismatches, and unauthorized server requests do not constitute a mismatch of certificate details. Therefore, focusing on the correlation between the certificate presented and the intended website is key to understanding the certificate mismatch warning.
