If I launch a simple version of the product without this feature (user story) will it affect my ability to prove or disprove that users want what I’m building? If the answer is NO, strike it. But, but, but, … if users cannot reset their password, they will have a bad experience. It’s not about proving the product is complete or comprehensive, but that what you are offering is what people want
