Is it possible to modify the portal to utilize a CDN to deliver the jquery, angular, and bootstrap content rather than from static/contrib/js? This could greatly improve the performance of the portal.
Welcome to privacyIDEA,
in many scenarios privacyIDEA is used within the local network with limited access on privacyIDEA and with limited access from privacyIDEA to the internet. This is one reason (besides for security reason) to choose the self contained design.
However, you can change the UI (including html templates) as you wish. Search for “customize” in the documentation:
