This question already has an answer here:
If you have taken the time to merge your MyOpenID StackOverflow (and StackExchange) account into a social network account such as Google or Facebook, can you describe the workflow (maybe with screen shots)? Many will be confused on February 1, 2014, so I thought having a question and some answers with a solution will be nice to have. I will take the time soon and do it myself. I'm sure there will be answers for the following account types, unless someone takes the time to answer for all of them. Facebook, Google, Twitter, LinkedIn, Yahoo
Note, this question doesn't show you the steps to merge, so it's not entirely helpful to save hundreds of millions of users time.

Quote from site above:
We have made the decision to end of life myOpenID, and the service will be turned off on February 1, 2014.
In 2006 Janrain created myOpenID to fulfill our vision to make registration and login easier on the web for people. Since that time, social networks and email providers such as Facebook, Google, Twitter, LinkedIn and Yahoo! have embraced open identity standards. And now, billions of people who have created accounts with these services can use their identities to easily register and login to sites across the web in the way myOpenID was intended.
By 2009 it had become obvious that the vast majority of consumers would prefer to utilize an existing identity from a recognized provider rather than create their own myOpenID account. As a result, our business focus changed to address this desire, and we introduced social login technology. While the technology is slightly different from where we were in 2006, we are confident that we are still delivering on our initial promise - that people should take control of their online identity and are empowered to carry those identities with them as they navigate the web.
For those of you who still actively use myOpenID, we can understand your disappointment to hear this news and apologize if this causes you any inconvenience. To reduce this inconvenience, we are delaying the end of life of the service until February 1, 2014 to give you time to begin using other identities on those sites where you use myOpenID today.
