Auth0 SAML IdP: Set Issuer to URL-based Format in the Metadata

Single Sign-On
Feb 20, 2026
Overview
The `issuer` attribute is set in the application's SAML add-on settings to a URL, which is reflected in the Entity ID in the SAML response.

The IdP metadata XML provided by Auth0, however, still returns the default issuer that's in URN format. Are we able to change the metadata issuer as well?
Solution
The Entity ID format is hardcoded and not configurable. Manually replace the Entity ID in the metadata once downloaded before configuring it in the service provider.
