Description
The current OpenID4VP implementation only supports the 'same device' flow where the wallet is an Nuts embedded wallet. To support both cloud wallets, same-device wallets and cross-device wallets:
- Allow user to choose device at verifier (Nascar signs)
- Allow verifier to make assumption based upon
wallet_hint(extension, skip Nascar signs) - Add example how verifier frontend and backend should communicate when using cross-device flow
- Expect user pin for cross-device flow
- Add user session at verifier (for reuse of user VP)
Some questions:
- display pin within verifier UI

Research direction
Start with the current OpenID4VP implementation and trace its same-device verifier and wallet flow. Done requires supporting device choice, wallet_hint handling, cross-device frontend/backend communication, a user PIN, and verifier-side session reuse; the issue does not name specific files or tests.
