Currently this tool will not ask for Jira credentials to integrate with Jira. It will use the authentication from browser. So before integrating this tool with Jira or use this tool for daily activities, user must be authenticated in Jira from the browser.
To remove this restriction this tool can get and store the Jira credentials. So that when ever the user is not authenticated in browser, this tool will automatically authenticate the user in Jira using the credentials.
