  General Two Higgs Doublet Models (2HDM) are popular Standard Model extensions
but feature flavor changing interactions and lack neutrino masses. We discuss a
2HDM where neutrino masses are generated via type I seesaw and propose an
extension where neutrino masses are generated via a type II seesaw mechanism
with flavor changing interactions being absent via the presence of a U(1) gauge
symmetry. After considering a variety of bounds such as those rising from
collider and electroweak precision we show that our proposal stands as a UV
complete 2HDM with a dark photon where neutrino masses and flavor changing
interactions are addressed. A possible dark matter realization is also
discussed.
