I have become a big proponent of OpenID lately. I think it is a great solution to the growing problem of managing your online identity and login across many sites.
Today, WordPress.com announced that they would begin supporting OpenID:
“OpenID is a new standard that hopes to alleviate some of the pain, and we’ve just made it available to everyone who has a WordPress.com blog. This means you can sign in to a growing number of sites using your existing WordPress.com account.” (Quote from WordPress.com)
This is great news, but so far, it looks like a one way deal. You can use WordPress.com OpenID credentials to log into other sites, but you cannot use other OpenID providers to post to WordPress.com:
“Unfortunately, you cannot login to WordPress (at least from what I can tell) with an external OpenID. This means that WordPress.com is just a provider of OpenID’s and not a consumer of OpenID’s. So I can’t use my MyOpenID or my LiveJournal OpenID post comments on WordPress.com blogs. Hopefully support for that will be coming soon.” (Quote from Scott Kveton, CEO of JanRain)
I suspect that WordPress.com is testing the waters by becoming an OpenID to provider as a first step. If it is successful, I would not be surprised if they decided to accept OpenID’s to login and post to WordPress.com.
