Now that I have a better understanding of how it works, (thanks Turbotodd) I am all over this OpenID thing. Doesn’t hurt that all the big players are sigining on as well ( Google, IBM, Microsoft, VeriSign and Yahoo! join OpenID Foundation Board.)
Having one place to sign in and one account to maintain is a great concept. And in my first experience using it, I did not need to read the accessibility-unfriendly captcha field to sign up. I know I have trouble getting those captchas right and I also have also heard from people who use pagereaders or have other accessibility concerns, that if they come across a captcha they just won’t sign up. So, I am thrilled to find another way of handling verification.
I am, however, having a hard time imaging how large enterprises are going to incorporate it. Especially considering the security concerns big businesses already have and my experience getting existing permissions systems to play nicely with other apps.
If we can all adopt it, I think OpenID would be a big step forward in authentication. I hope to see it happen.
