&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;lt;&amp;lt; Back to [[Baseline_Functional_Requirements_v1.0|Baseline Functional Requirements Index]]&amp;#039;&amp;#039;&lt;br /&gt;

== INTEROP-2.    THIRD PARTY CREDENTIALS ==&lt;br /&gt;
Entities who issue credentials or assertions MUST issue them using content and methods that are capable of being consumed for multiple purposes and multiple recipients.&lt;br /&gt;
&lt;br /&gt;
=== SUPPLEMENTAL GUIDANCE ===&lt;br /&gt;
This Requirement applies to entities that issue identity credentials and/or assertions and requires that the credentials/assertions issued by such entities may be accepted by multiple [[IDEF Glossary THIRD PARTIES|THIRD-PARTIES]] (such as [[IDEF Glossary RELYING PARTIES|RELYING PARTIES]]). This does not require that such credentials/assertions must be accepted by all THIRD-PARTIES; rather, the Requirement is that credentials/assertions may be accepted by multiple (more than one) [[IDEF Glossary THIRD PARTIES|THIRD-PARTIES]]. Single-purpose Identity credentials/assertions that are used exclusively for access to a single enterprise/online resource that are not permitted for authentication by any external THIRD-PARTY would not conform to this Requirement.&lt;br /&gt;
&lt;br /&gt;
This Requirement addresses the format or expression of the credential or assertion data itself and policies for its use, and not its method of exchange, which is addressed in [[Interop Req 4|INTEROP-04 (STANDARDIZED DATA EXCHANGES)]]&lt;br /&gt;
