Fat Cookie

The 'Fat Cookie' refers to a modified version of a normal browser cookie that is encoded and digitally signed. The fat cookie contains biographical information about the user. It allows services not deployed on specific ITS-administered machines to use UT EID logon authentication.

If you are interested in setting up the infrastructure necessary to begin accessing the fat cookie on your own server, you will need to contact the ITS EID Team, who can provide you with software for the scripting language that you are using.

Once you have set up the infrastructure to read the fat cookie, you can access the following fields:

  • Name

  • UT EID

  • UIN

  • Assurance level

  • Cookie expiration time

  • Number of roles

  • Roles (In the format Component-Role-Status)

  • IP address

  • Cookie status

  • Keyid

  • Version
