Reusable identity credentials

A reusable credential lets a person present signed attributes that were previously verified by an issuer, reducing the need to repeat document-and-selfie proofing for every service. The relying party still has to trust the issuer, validate the presentation and request only necessary data.

For: identity architects, product, privacy, fraud and procurement teams. This is independent information, not legal, compliance or security advice.

Repeated proofing versus presentation

Repeated proofing	Reusable credential
Service or vendor rechecks raw evidence	Issuer previously checked and signed attributes
Often collects full document/selfie	Can request selected attributes
Service assesses document and holder	Verifier assesses issuer trust, status and presentation

Trust questions remain

• Who issued the credential and under what assurance?
• Is the issuer trusted for this attribute and jurisdiction?
• Is the credential authentic, current and not revoked?
• Is the presentation bound to the holder and transaction?
• Does the credential answer the service decision without extra data?

Privacy opportunity

Selective disclosure and derived attributes can reduce repeated collection. That benefit is lost if relying parties request full identity data by default, correlate presentations unnecessarily or retain every disclosed value indefinitely.

Transition design

Run credential presentation alongside suitable existing methods while adoption grows. Compare fraud, completion, cost, support and privacy, and ensure the fallback does not become a lower-quality or punitive journey.

Evidence and limits

MyID separates enacted rules, official implementation material, testing and vendor claims. A source can establish what its publisher says; it does not prove that every product, deployment or interpretation works as claimed. Where Irish implementation remains unsettled, this page says so.
