i am login first time on automation edge community server how to get login credentials from tenant admin or user please help
Not sure what you are requesting. If you registered for the community license, you should use the same credentials to login as Admin tenant and be able to create users at will.
From there you can download Process Studio to start creating WF.
Maybe you could clarify a little more what the issue is. Where in the process are you locked out to do your stuff.
You can connect with Training team to get the AutomationEdge credentials.
