CoGe user
From CoGepedia
CoGe's user account system is run using the iPlant authorization system. If you have an iPlant account, you can use those credentials to log into CoGe.
Pressing the "sign-in" link will take you to iPlant's authentication service. Type in your iPlantID and password. If you are validated, you will be returned to CoGe. When you return, your name and a logout link should appear instead of the login.
