Federated Identity - CI/CD Glossary Definition
Federated identity lets one system trust identities issued by another, so a token from a trusted identity provider is accepted without the resource maintaining its own credential store.
Trust relationships
Federation is configured by declaring which issuers and which claims to trust. The resource verifies the token signature against the provider rather than a local password.
In CI/CD
Cloud OIDC federation trusts GitHub Actions or a managed runner as an identity provider, exchanging its token for temporary cloud credentials.
