Many models beyond the standard model predict new particles with long lifetimes, such that the position of their decay vertex is measurably displaced from their production vertex. The decay of such feebly interacting particles gives rise to non-conventional experimental signatures. An overview of recent searches for long-lived particles is presented. The results are obtained with the data collected by the CMS experiment during Run 2 (2016-2018) and Run 3 (2022) of the CERN LHC. A discussion on the triggers operating during Run 3 and designed to target the signatures of the decay of long-lived particles is also provided.
