Hi Heidi,
The documentation you are seeing is from OutSystem 11.
Seems like, looking for your service center print screen, that you are using OutSystems 10. Is that right?
If this is the case check the documentation about 'Secure the Application' for version 10:
https://success.outsystems.com/Documentation/10/Developing_an_Application/Secure_the_Application
This functionality seems to not be available in version 10.
If possible try to upgrade it to 11 to use it.
Hope it helps :)
Cheers and Regards,
RR
