He got SPSM thanks to the Six Paths Sage Chakra, he also awakened SPSM once he had Hag's chakra, Naruto and Sasuke each have their own Six Paths Chakra thanks to awakening the Rinnegan and SPSM. Naruto can't lose SPSM because he generates his own Six Paths chakra. You can't lose something you awaken in your own body, they may be weaker than when they had Hag's chakra since they no longer have it, but that doesn't mean they lost their SPSM or Rinnegan.
