We have a scenario where we log in users into our custom application (and custom login) and there they can check the issues allotted to them. These issues are taken from Jira and the issue tracking system we're using is Jira. However, We're unable to get the Auth token of each user, as there are no ways to get the Auth token through password grant. Is there any way I can get the Auth token to make API calls on behalf of my logged in user to make API calls?
