  Scotogenic is a scheme for neutrino mass generation through the one-loop
contribution of an inert scalar doublet and three sterile neutrinos. This work
argues that such inert scalar doublet is a Goldstone boson mode associated with
a gauge symmetry breaking. Hence, the resultant scotogenic gauge mechanism is
very predictive, generating neutrino mass as contributed by a new gauge boson
doublet that eats such Goldstone bosons. The dark matter stability is
manifestly ensured by a matter parity as residual gauge symmetry for which a
vector dark matter candidate is hinted.
