In this paper, we discuss the impact of neutrino phenomenology and related cosmology on an A 4 ⊗ Z 8 symmetric ν 2HDM along with an addition of a new particle, i.e. a gauge singlet (S). The additional particle is a sterile neutrino which is considered to be a probable dark matter (DM) candidate in our work. With the choice of sterile neutrino mass in keV range, we evaluate the active-DM mixing angle, decay rate and relic abundance considering various cosmological constraints. Simultaneously, a detailed analysis on baryogenesis and neutrinoless double beta decay is also carried out for low-scale right-handed neutrino masses. We have considered various bounds from experiments such as Lyman- α , X-ray observation, Planck data and KamLAND-Zen limit to validate the model with respect to the phenomena studied in it.
