Verify Identity

# Verify Identity: Password Re-auth

## Context
Flexnative UI intent — a reference solution from the shadcn/ui registry (@flx). The intent frames the problem; the decision is one approach to it.

## Problem
Re-confirm the person behind an already-signed-in session before a sensitive action, without forcing a full sign-out.

## Decision
- Best for: The lightweight default for step-up. Re-prompt the current password before money moves, settings change, or data is exported. No new channel, no new hardware.
- Trade-off: Only as strong as the password itself, so it adds little for accounts already protected by one; useless for passwordless users.

## Registry Item
@flx/verify-identity-1

## Stack
- UI: shadcn/ui
- Styling: Tailwind CSS
- shadcn components: Button, Card, Input, Label
- npm: lucide-react
