5.6 Multiple Subscriber Account Scenarios

Some CSPs need to support a single user’s ability to interact with the CSP while fulfilling different roles or personas. For example, a subscriber may interact as themselves and also as a representative of a business across different services supported by the CSP. Another scenario is a CSP that serves both commercial and federal RPs and must maintain a separation between its services. To limit fraud and avoid redundant costs and processes, CSPs SHOULD provide users with a means to manage multiple user personas without having to create multiple subscriber accounts. If this is not possible, and multiple subscriber accounts are supported for a single subscriber, the CSP SHOULD implement its subscriber accounts in a manner that avoids unnecessary re-proofing of the same subscriber (e.g., linking accounts via a common identifier or through biometric or attribute resolution).

If multiple subscriber accounts are permitted for a single subscriber, the following requirements apply:

Similar scenarios can also occur when RPs use the services of multiple CSPs. This is known as account linking, and Sec. 3.8.1 of [SP800-63C] describes the association of an RP subscriber account with multiple CSP/IdP accounts.
