Here, in an analysis of a 2.92 fb–1 data sample taken at 3.773 GeV with the BESIII detector operated at the BEPCII collider, we measure the absolute decay branching fractions to be B(D0 → K–e+νe) = (3.505 ± 0.014 ± 0.033)% and B(D0 → π–e+νe) = (0.295 ± 0.004 ± 0.003)%. From a study of the differential decay rates we obtain the products of hadronic form factor and the magnitude of the CKM matrix element $$f$$ $$^{K}_{+}$$(0)|Vcs| = 0.7172 ± 0.0025 ± 0.0035 and $$f$$ $$^{π}_{+}$$(0)|Vcd| = 0.1435 ± 0.0018 ± 0.0009.
