@Bolt Hagoromo gave Naruto his Six Paths Senjutsu Chakra and gave Sasuke the Six Paths Power. Which allowed Naruto to awaken SPSM and Sasuke to awaken his special Rinnegan. Hagoromo didn't specifically give Naruto and Sasuke all of their new techniques, he just gave them his chakra which allowed them to awaken new abilities and techniques.
