Neutrinos are the only standard model particles of unknown mass. Thus, measuring their mass is one of the leading goals in fundamental physics. Cosmology currently provides the tightest bounds on the sum of the neutrino masses and the possibility that next generation experiments can provide a detection looks promising. Then, further questions would have to be addressed, such as the neutrino hierarchy and the neutrino nature. In this talk, I will discuss the treasure trove of information about massive neutrinos that we can collect from different cosmological probes. I will stress the importance of extending our interest to laboratory searches, such as kinematic measurements and neutrino less double-beta decay experiments, for going beyond measuring the neutrino mass. Finally, I will choose a different angle and show how massive neutrino unknowns can affect the constraints on inflationary models.
