Credential databases are digital repositories that store, organize, and provide access to records of academic, professional, or skills-based credentials. These systems may contain degrees, certificates, microcredentials, licenses, badges, or verified learning records.

Credential databases support credential verification, portability, and interoperability across educational institutions, employers, and digital wallet systems. They may operate at institutional, state, national, or international levels and increasingly connect with Learning and Employment Record (LER) systems and digital credential standards.
