Hey! I have a couple of projects: main.com, proj1.com, proj2.com, proj3.com. I wanted to make it so that main.com hosts all the authentication accounts, and then the projects can sign in/sign up and share the information like first name and last name. This way I can continue to add more projects without touching auth at all and instead just have to quickly implement an sdk. Is SuperTokens a good way to do this? I was thinking the multi-tenancy thing, but I'm not sure
