Institution-owned digital credentials

A university owns a digital credential program when it controls the issuer identity, signing authority, verification service, credential status, and export path. Software can support that work, but the institution must define the policy.

Five controls that make credentials durable

Ask for named owners, documented recovery paths, and testable evidence for each control. A valid badge does not prove that the institution can correct, verify, or preserve its records over time.

Issuer identity
Keep the public issuer identifier and its recovery process under institutional control.
Signing authority
Define who can use, rotate, suspend, and recover the keys that sign credentials.
Verification
Provide a public, documented route that checks the proof and current credential status.
Credential records
Preserve evidence, approval history, lifecycle changes, and corrections as institutional records.
Exit control
Export credentials, templates, evidence references, status history, and verification documentation before a platform change.

Evaluate the full credential lifecycle

During procurement, follow one representative credential from approval through issuance, verification, correction, and a possible platform transition.

Review the Open Badges 3 governance guide
  1. Step 1

    Issue a representative credential

    Use a real policy, named issuer, evidence record, and approval path. Confirm what becomes public before the learner receives it.

  2. Step 2

    Verify outside the issuing system

    Check the public page, machine-readable export, proof, and current status in a separate browser session or with an independent verifier.

  3. Step 3

    Test a change and an exit

    Suspend or revoke a sample credential, restore it when policy permits, then export the program record and document how verification will continue after a platform change.

Evidence that can be inspected

Review standards requirements, product capabilities, implementation evidence, and certification claims separately. Each supports a different procurement decision.

  • Open Badges 3.0 requirements

    The specification and conformance guide define credential roles, verification, status, and certification expectations.

  • Verifiable Credentials model

    The W3C model defines the credential, issuer, subject, proof, and credential-status concepts used across credential ecosystems.

  • CredTrail public source code

    Longsight publishes CredTrail’s source code so institutions can inspect or run its verification and credential-lifecycle implementation.

Where CredTrail fits

CredTrail is Longsight’s open-source credential product. Its product pages and documentation describe its support for governed issuance, public verification, wallet delivery, and institution-controlled deployment.

Longsight’s institutional guidance explains what a university should own and test, whether or not it selects CredTrail.
