# UM Web SSO — institutional SAML 2.0 / OpenID Connect identity provider

**Canonical:** https://apis.io/apis/university-of-macau/websso-idp/  
**Provider:** University of Macau — https://apis.io/providers/university-of-macau/  
**Documentation:** https://websso.um.edu.mo/adfs/ls/IdpInitiatedSignon.aspx

UM Web SSO — institutional SAML 2.0 / OpenID Connect identity provider is one of 9 APIs that [University of Macau](https://apis.io/providers/university-of-macau/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, SAML, OpenID Connect, and Education. The published artifact set on APIs.io includes authentication docs.

UMPASS, the university's single sign-on, is served by UM's own AD FS farm. It publishes federation metadata as application/samlmetadata+xml — 71 KB, signed, carrying both an IDPSSODescriptor and an SPSSODescriptor, SAML 2.0 protocol support, SingleSignOnService over HTTP-POST and HTTP-Redirect, four SingleLogoutService endpoints and 128 declared claim types — and an OpenID Connect discovery document at /adfs/.well-known/openid-configuration. This is the university's strongest institution-operated machine-readable surface and the one class the June 2026 cohort profiling missed entirely. Macao has no national research-and-education identity federation, so there is no eduGAIN or InCommon aggregate entry to point at; the metadata is published directly by the institution.
