I don&#x27;t think they&#x27;re missing it. It&#x27;s a bad idea and you can have your own valid certificate for free from many companies. Or for test, you can create your own cert in 2 lines of bash. (and add the ca to trusted store, so it&#x27;s just as valid as this one)<p>For testing purposes you can also generate your certs valid only for a few hours&#x2F;days, so you can be sure they never get used in production by accident. And with proper SAN entries.
