The option to save an anonymous CodePen is no more.

As of today, login is required to save any content on CodePen.

I know it’s not a good idea to rely on third-party infrastructure, however for my students trying out HTML and CSS with CodePen now became a wee bit uncomfortable. And I totally understand the rationale behind this move. The reasons (idiots like spammers, scammers, abusers) are why we cannot have nice things.
