Hello @randika96, welcome to the OpenMRS community!
To gain access to JIRA using your newly created OpenMRS ID, you must first create a case with the helpdesk at help.openmrs.org stating that you’d like accss to JIRA. This is a simple step the organization takes to prevent spam accounts and only takes a minute to complete but may take a few hours to receive your access.
Thanks and looking forward to seeing you in our community
