As we've seen with Stack Exchange, OpenID is confusing for most users, but good news: you don't need a Google or Facebook account anymore! You can sign up for a Khan Academy account with any email address here:

Off topic, but can you add the ability to check off completed videos instead of having to watch them within the website? I usually play KA videos at 1.5x or 2.0x on youtube, but then I don't receive any points :(

Thanks for everything by the way.

Cool - when did that happen?

Thanks for pointing out :)

I don't remember exactly, but it was a few months ago. About a month ago we also launched the ability to create "child" accounts for under-13 users who aren't old enough for Google or Facebook accounts.

It would be cool to be able to transition accounts to the new child accounts; is that possible?

Sorry, it's not possible, but the main reason to create a child account is to get around the Google/Facebook requirement -- since you've already surmounted that hurdle, a child account probably wouldn't be of any more use to you.

OpenID is dead. It was flawed from the beginning, they botched the deployment, and it's useless outside of the you-sitting-in-front-of-browser context. Mobile apps, delegating access, exchanging profile data... not supported.

So what is a better solution? Genuine question.

The only thing that works well for lots of people is Facebook, twitter and google login. Mozilla's browserID might change things, but I'm neither holding my breath or expecting it to work well anytime soon. This is Mozilla after all.
