Distinct kind of auth

[thoysh]

Hi! This package is truly awesome! I already used it in one project successfully, but I brought it to my job and I'm facing an issue.. There is a access control platform in my company which uses some IT json configurations to do a POST request on some internal REST API. So I won't have access to users database, instead, I should have the possibility to get username and password data to do this API request to check if the user is authenticated. Is there a way to do it with shinymanager?
