User Story: "As a PO, I want to have an authentification on the poll creation page, so I can login to my account."
I see 2 errors:
* As a USER not PO, typically the product owner is not a typical type of user
* Login to my account is a goal not a good reason to get the functionality. Reason could: ... so that I have access to my user data etc.
Do you agree? What else do you suggest?
