Credential portability is the property that lets a holder carry verifiable credentials across providers, platforms, and jurisdictions without re-issuance or vendor lock-in. It relies on open standards such as W3C Verifiable Credentials and decentralised identifiers so that issuers, holders, and verifiers interoperate. It is a foundational capability for user-controlled digital identity and trust frameworks.

- Portability depends on standardised credential formats, cryptographic proofs, and agreed governance so that a credential issued in one context is trusted in another. It reduces lock-in and re-verification cost while preserving holder control, but requires shared schemas, revocation infrastructure, and aligned legal recognition across domains.
