Digital Identity Wallet
A digital identity wallet is an app that lets its holder store credentials and attributes about themselves or their organisation, and choose exactly what to share with a relying party, keeping the holder in control instead of a central registry.
Digital identity wallet is the general category; the EUDI Wallet is the European Union's specific, regulated implementation of it, mandated for every member state under eIDAS 2.0. Wallets from other jurisdictions or private vendors follow the same holder-controlled model but different technical and legal rules, so a credential built for one wallet ecosystem does not automatically work in another unless both implement a shared standard such as OpenID4VCI or ISO 18013-5.
