↗SOURCE-BOUND REFERENCE
SSO & ShareInfo: two concepts, not synonyms
Source → Scope → Evidence → Limitation
SSO
SSO establishes an authentication/session context using the integrated mechanism.
ShareInfo
ShareInfo is an authorized attribute-sharing step when the source/service permits it.
Consent
Consent/authorization is tied to purpose and relying party, not merely to the fact that a user signed in.
Attribute minimization
A relying party should request only attributes needed for purpose rather than a complete profile by default.
Correlation
Where sourced, transaction/session/process identifiers make the attribute-sharing context auditable.
Privacy boundary
Raw tokens/credentials and sensitive data payloads are not exposed on the public site.
