The Yahoo OP is officially live today! Congrats to Shreyas and Allen for shepherding this for many months!

If you’re a Flickr user you can your photos URL (http://flickr.com/photos/yourname), or if you’re signing into a RP that supports XRDS, just use flickr.com.

You’ll also want to visit openid.yahoo.com, and click on “Get Started” and customize your OpenID identifier.

Personally I just use laughingmeme.org as my OpenID. I had to futz around a bit to figure out OpenID 2.0’s slightly different syntax, but if you view source on this blog you’ll now see in the header:

<link rel="openid2.provider" href="https://open.login.yahooapis.com/openid/op/auth">
<link rel="openid2.local_id" href="http://www.flickr.com/photos/kellan">
