 There are many situations in which it is desirable to transfer a copy of a digital credential to another person. For example, you may want to provide access to your vehicle to a friend or a family member. You may also want to provide access to your home to your cat sitter. Or, you may want to transfer a copy of a hotel key to your spouse. Today, no such standardized method exists in a cross-platform, credential type-agnostic capacity.

 - Allow a recipient to view the share request, and provision the credential associated with the share upon receipt
-- Allow opaque message content based on the credential type (the protocol should be able to carry various types of credentials)

-- The User Interface (UI) that is displayed to the sender or receiver during sending or receiving - this will depend on the device OEM’s UI and HI guidelines.

 The WG will deliver a protocol to facilitate secure credential transfer. The WG must consider all Privacy and Security considerations in an effort to perform the credential transfer in a secure manner. The protocol will use appropriate cryptographic mechanisms to protect the transferred credentials in accordance with the security and privacy goals described above.
