The IdP will typically have a long-term relationship with the client. This relationship typically involves the IdP positively identifying and credentialing the client (for example, at the time of employment within an organization). When dealing with Individuals, this process is called "identity proofing" [NIST-SP.800-63-2]. The relationship will often be instantiated within an agreement between the IdP and the client (for example, within an employment contract or terms of use that stipulate the appropriate use of credentials and so forth).
