Abstract: The observation of neutrino oscillations provides striking evidence for physics beyond the Standard Model. While multiple neutrino experiments continue to constrain oscillation rates and mass values, one fundamental question remains unanswered: How do neutrinos get their mass? Many theoretical models exist, but so far none of them have been experimentally confirmed. In this talk I will give an overview of different neutrino mass mechanisms and discuss the prospects of distinguishing Dirac from Majorana neutrinos.
