# SIP Domain Registration CredentialListMapping Resource

The SIP **Domain Registration CredentialListMappings** subresource represents the CredentialList instances associated with this domain's registration.

If a domain registration is received for a domain with a Credential List mapped to it, Twilio will challenge the request. Your system will need to authenticate with a username and password. The username and password must be in one of the mapped lists for the registration to be accepted
