This is a gallery of innovative signin and registration experiences that leverage user managed identity - enabling folks use existing accounts with one organization to authenticate on other websites. There are a variety of user interface approaches that make the most of this capability, the following are just a few examples.  We'd love to hear your thoughts on what works and how organizations could make the experience even better.  To leave feedback, please visit our idea forum.
