In addition to user management of their credentials, there is an admin flow for administrators to manage other users' credentials. Specifically, to search for and remove a user's registered credential from the system.
The management flow can be accessed by navigating to:
http[s]://hostname/idp/profile/admin/webauthn-management
As with the registration flow, the management flow will use whichever authentication method is enabled. Importantly, the client and user accessing the management function are subject to an AccessControlConfiguration set by the property idp.authn.webauthn.admin.management.accessPolicy; by default, this is the AccessByAdminpolicy. Given the purpose of this flow, it is important to ensure a suitably restrictive access policy is set. Furthermore, it is essential to ensure that an appropriate authentication method is executed, even if a fallback has been configured for administrators lacking FIDO2 credentials. This is controlled by the idp.authn.webauthn.admin.management.defaultAuthenticationMethods property, which defaults to saml2/<http://example.org/ac/classes/mfa>. This default setting is intentional, careful consideration should be given if you change this setting.
The process is straightforward: initially, you search for a user by their User Name to display their registered credentials. Subsequently, you have the option to delete one or more of these credentials before completing the process.
