Normalized User Profiles
The normalized user profile is an Auth0-specific way of standardizing and storing user-related information. Because every Identity Provider (IdP) provides a different set of information about a user, Auth0 normalizes common profile properties into a protocol-agnostic representation of the user when storing user-related claims. For example, family_name in the normalized user profile contains details that may be returned to an IdP as surname or last_name.
As such, the Auth0 claims included in the normalized user profile differ from the standard set of claims that can be returned in ID Tokens from the Authentication API's oauth/token endpoint or in the response from the /userinfo endpoint (both of which follow the requirements detailed in the OIDC specification).
