We study the phenomenology of the scotogenic model in the case of a Majorana dark matter (DM) candidate. This scenario gives important consequences since the parameter space of the model is almost unconstrained compared to the inert Higgs doublet model (or the scotogenic model with scalar DM) and hence offers new opportunities for discovery at future high energy colliders, e.g., the HL-LHC. As an example, we focus on the production of the Standard Model (SM) Higgs boson in association with a pair of dark scalars. Owing to its clean signature, the γγ decay channel of the SM Higgs boson is investigated in great detail at both the HL-LHC (at s=14 TeV) and the future FCC-hh (at s=100 TeV). After revisiting the LHC constraints from run II on the parameter space of the model and selecting benchmark points satisfying all the theoretical and experimental constraints, we found that scalars with mass up to 140 GeV (160 GeV) can be probed at the LHC (FCC-hh) with a 3 ab-1 of integrated luminosity assuming a total uncertainty of 5%.
