We're pleased to announce that startingtoday, you will be able to register and log in to the T-Mobile Support Community using your login information from some of your favorite sites, such as Yahoo, Facebook, and more! Also, if you are already a registered member, have no fear, because you do not need to re-register using the social login.
Having to create a separate login for every site you visit can be a hassle, and we know that. This is exactly why we've added this new functionality to offer a fast, easy, and secure way for you to log in to our Support Community using the same login that you use everyday on your social site of choice.
You can find all the information you need to get going with the new social login here: About social login.
