Hello,
There is a FAQ about this topic in the Orthanc Book:
https://book.orthanc-server.com/faq/improving-interface.html
“Non-technical audience (physicists, patients, administrative staff…) might expect an user interface that is more user-friendly than Orthanc Explorer, and/or that integrates more features (such as […] login/logout).”
Please carefully read this page.
