### Description

We discuss the QCD phase diagram in the presence of a strong magnetic background field. We provide numerical evidence, based on lattice simulations of QCD with 2+1 flavours and physical quark masses, for a crossover transition at $eB = 4$ GeV$^2$ (with a pseudo-critical temperature $T_c = (98±3)$ MeV) and for a first order phase transition at $eB = 9$ GeV$^2$ (where the measured critical temperature is $T_c = (63±5)$ MeV). We conclude that the critical endpoint is located at $eB=eB_{CEP}$ and $T=T_{CEP}$, where $4$ GeV\$^2
