EUDI wallet relying party registration: what changes for IAM teams?

TL;DR: EUDI wallet relying party registration is needed to stop fraud and abuse by letting wallets verify which organisations are legitimate, what they may request and why, while Member States build national registers for cross-border trust and automated checks, according to Procivis. The control shifts trust from self-assertion to registry-backed authorisation, which is the only workable model at EU scale.

Key questions

Q: How should organisations govern wallet relying party access in digital identity ecosystems?

A: Treat relying-party access as an authorisation problem, not only a registration exercise.

Q: Why do wallet ecosystems need a public relying party register?

A: Because a wallet can only protect the user if it can verify who is asking before data is shared.

Q: What breaks when relying parties are not registered before wallet use?

A: The trust model collapses into ad hoc judgement at the point of disclosure.

Practitioner guidance

• Define the relying-party approval workflow Map who can approve, what evidence is required and which services may request which wallet attributes before any registry goes live.
• Build machine-readable trust lists Publish registry entries in signed, queryable form so wallets can verify authorisation automatically rather than relying on manual checks.
• Separate authentication from authorisation Make sure wallet authentication does not substitute for a relying-party permission check, especially when attributes are sensitive or jurisdiction-specific.

Bottom line: Wallet-based identity is only safe when the requesting organisation is also governed, not merely identified.
