Digital Product Passports: what they mean for identity and access

TL;DR: The EU’s Digital Product Passport framework ties product traceability, lifecycle data, and role-based access into a regulated digital identity layer for batteries, textiles, steel, and other categories, according to Namirial. The governance challenge is no longer just product transparency; it is proving who may write, read, and update trusted product records across the supply chain.

Key questions

Q: How should organisations govern access to Digital Product Passport data?

A: They should treat access as role-scoped and assurance-based, not as a simple portal permission.

Q: What breaks when product identity is not standardised in a DPP programme?

A: Interoperability breaks first, followed by traceability and reliable updates.

Q: Why do trusted digital identities matter for registry-based compliance?

A: Because the registry only has value if the system can prove who is acting and whether that actor is allowed to register or update data.

Practitioner guidance

• Define DPP ownership and update rights Map each product category to the organisation that owns the passport data, the actors allowed to update it, and the events they may record.
• Bind product records to trusted identifiers Use a stable identifier scheme that can connect the physical item, batch, or model to the digital passport across manufacturing, logistics, and retail systems.
• Require assurance before Registry access Set access rules so that only verified economic operators and authorised stakeholders can query or modify Registry data.

Bottom line: Digital Product Passports shift product compliance into a governed identity and access problem across the supply chain.
