Can you share the same account on PSVita with other PS Consoles?

I used to have a PSVita but I ended up giving it to my little brother after I grew old enough to not want it anymore, and I'm thinking of buying another one for myself (mostly because I don't really wanna accidently do something to his games/saves, or something like that). And if I do end up buying a new one, I wanna make sure, can you share the same account on a PS4PS5 and on the PSVita? If so, how?
