I just realized OAuth support is slated for inclusion in WordPress 2.7. It’s not in trunk yet, but that’s no reason not to get up to speed. Scott Gilbertson says OAuth and OpenID are foundations to the open social web, giving apps like WordPress a “secure, centralized means of identifying yourself and a way to control who knows what about you.”
Chris Messina, who says we currently treat user credentials “like confetti,” is more than a little excited and is building a series of WordPress Plugins to take advantage of these formats. Stephane Daury is excited too.
