It's a question that comes up quite a bit, and this is an attempt at providing some very concrete suggestions.

Holy crap, I guess the whole "if you don't ask, you don't get" is real! Apple couldn't fix my 3-year-old out-of-warranty Studio Display so in the end they replaced it. For free! It feels like Christmas.

Say hello to auth flows without redirects! 💜
🆕 Expo Router’s new protected routes offer a more declarative way to manage access in your navigation structure. With protected routes you can:
♢ Define auth flows clearly and predictably
♢ Avoid imperative redirects
♢ Easily control nested routes and modals
