hey Jon! Quick background on where it is coming from - there was a request from SNOMED folks to enable security on OHDSI ATLAS due to the SNOMED license restrictions. We are actively discussing different options at this moment on how to make it less intrusive and user friendly. Unfortunately, I do not think any of the are particularly simple to implement (if done properly) or user friendly (if it is a quick fix).
@lee_evans have put such a quick fix in place for the time being. But I would propose we either disable it - until we figure out a more user friendly option - or maybe post the information somewhere on what the user name / password is?
