Login on different sites with one account

Question

I have written several different sites with asp.net core and I want to write a site called Account.MYSITENAME.com where users can only register and by logging in, they will stay logged in on the rest of my sites. Like Google, you can only log in to all Google services with Gmail. how to implement such a thing in asp.net with identity?
