We consider an extension of the standard model with three Higgs doublets and S3×Z2 discrete symmetries. Two of the scalar doublets are inert due to the S3 symmetry and the Z2 symmetry ensures that the right-handed neutrinos generate active neutrinos masses at one-loop via the scotogenic mechanism. We have also calculated all the mass spectra in the scalar and lepton sectors and accommodated the leptonic mixing matrix as well. Constraints on the parameters of the model coming from the lepton flavor violating decay μ→eγ are obtained, using the current and the upcoming experimental limits. We also use those constraints to predict the induced μ→eee¯ channel at one-loop.
