Unico Identity OAuth2 is one of 3 APIs that [Unico](https://apis.io/providers/unico/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Authentication, OAuth, and OpenID Connect. The published artifact set on APIs.io includes API documentation and authentication docs.

The OAuth2 token service every IDCloud contract authenticates against. Implements the RFC 7523 JWT-bearer grant with an RS256-signed assertion exchanged for a one-hour access token, and serves a live OpenID Connect discovery document. Served from acesso.io, Unico's own former Acesso Digital domain, which Unico's published Environments page names as the production token host for every contract.
