How can I view my own security role?

Your security role gets indicated on your staff profile. To see what your security role is, you'll need to click on the upper right and select My Profile from the dropdown menu that appears - 

You can find the Security field either on the left side of your staff profile under the Email field or in the Overview section directly above Accepts Appointments. 

Unless your account has some custom security roles that have been added, you will be listed as having 1 of these security roles - 

1. Account Owner
2. Administrator
3. Location Super User
4. User
5. Checkin Only
6. Reports Only
