Holy Crap!
Just last week, I asked Google to add OpenID support to Blogger. Today, I was posting a comment on Renee’s blog and there is now an option to sign-in using OpenID! I never knew I had such power.
Update: Ok, apparently they’ve been testing it publicly since November but I’m sure I must have had something to do with it.
Could you please use your awesome power to explain to me how to use OpenID? When I tried to sign in here, it asked me for my OpenID URL. I tried www.blogger.com, www.blogspot.com, and www.unrulyduckling.blogspot.com, but I could not appease the log in deities. What was I supposed to type there?
Currently, Google is only using OpenID for making comments on Blogger.com blogs. They are not publishing as an OpenID provider to allow you to use your Blogger account on other blogs. They say they are working on it.
In the mean time, you can use your LiveJournal (username.livejournal.com). Alternately, one of the cool things about OpenID is that it supports redirection. This means that any web url that you have control over (such as on Blogger) can be used as an OpenID. Basically, you would add something like this to the head section of your Blogger template:
You can also sign up for a generic OpenID provider, I like MyOpenID.com, and then delegate it or use it directly.
