He got SPSM thanks to the Six Paths Sage Chakra, he awakened SPSM once he had Hag's chakra just like how Ashura awakened SPSM thanks to his Dad Hagoromo giving him his 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 thanks to awakening SPSM. You can't lose something you awaken in your own body, they may be weaker than when they had Hag's direct chakra since they no longer have it, but that doesn't mean they lost their SPSM or Rinnegan, Madara awakened Six Paths Chakra along with the Rinnegan too.
