  Electroweak baryogenesis is severely challenged in its traditional settings:
the Minimal Supersymmetric Standard Model, and in more general two Higgs
doublet models. Fine tuning of parameters is required, or large couplings
leading to a Landau pole at scales just above the new physics introduced. The
situation is somewhat better in models with a singlet scalar coupling to the
Higgs so as to give a strongly first order phase transition due to a tree-level
barrier, but even in this case no UV complete models had been demonstrated to
give successful baryogenesis. Here we point out some directions that overcome
this limitation, by introducing a new source of CP violation in the couplings
of the singlet field. A model of electroweak baryogenesis requiring no fine
tuning and consistent to scales far above 1 TeV is demonstrated, in which dark
matter plays the leading role in creating a CP asymmetry that is the source of
the baryon asymmetry.
