Verify Device
A sign-in approval flow where a trusted device shows an alert, then a code to enter on the new device.
Verify Device is an open-source mobile screen from suiss/uim for React Native and Expo, with SwiftUI and Jetpack Compose versions built from the same design tokens. The @esuiss/uim CLI copies its source into your project, so you own the code.

import androidx.compose.foundation.layout.BoxThe screen shows a mock alert from the trusted device with Allow and Don't Allow. Allowing reveals a code and an InputOTP to enter it, with a Spinner while checking and an error for a wrong code; denying shows a blocked message with an option to show the request again. A correct code shows an approved screen.
Installation
