Login component for Expo
Build a login screen in Expo, the right way: what it needs, how Expo handles it, and a prompt that starts from a real design so the first result already looks shipped.
What a login includes
A login is the screen where a user signs in or creates an account. The parts that matter:
- email and password fields
- social sign-in buttons (Apple, Google)
- a forgot-password link
- inline validation and error states
- a switch between sign in and sign up
Building it in Expo
In Expo, you React Native with batteries included: routing, builds, and OTA updates handled for you. The fastest way to a runnable cross-platform app. The fastest path is not to hand-place every element from scratch, but to give the builder a real login design to match. A vague prompt produces a generic screen; a concrete reference produces one you would ship.
That is what VP0 is for: a free library of iOS app designs built for AI builders, where every design has a machine-readable source page your tool can read from a pasted link. Pair it with Expo and the first generation matches a proven layout.
Prompt to build it
Paste this into your AI builder, with a VP0 login design link in place of the placeholder:

Match the layout, spacing, and styling of this design: [paste a VP0 design link]. Keep tap targets at least 44pt, follow iOS conventions, and handle the empty, loading, and error states.
Where a login shows up
