  We review the mechanism of electroweak baryogenesis. Our focus is on the
derivation of quantum transport equations from first principles within the
Schwinger-Keldysh formalism. We emphasize the importance of the semiclassical
force approach, which provides reliable predictions in most models. In the
light of recent electric dipole moment measurements and given the results on
new physics searches from collider experiments, the status of electroweak
baryogenesis is discussed in a variety of models.
