With iOS, it’s possible to set the keychainAccess option to something like Expo.SecureStore.WHEN_PASSCODE_SET_THIS_DEVICE_ONLY, which improves security for sensitive items by guaranteeing that items in the store can only be accessed when the device has a passcode set. However, it doesn’t seem like there’s a similar option in SecureStore for Android. Native Android does have a mechanism for only allowing a key in the keystore to be accessed when the user has authenticated via passcode/pattern/etc -- it would be nice to have this implemented as an option in SecureStore.
