Does a machine have to be domain joined in order to use Direct Access

Question

Does a machine (e.g., mobile laptop) have to be domain joined in order to use Direct Access (DA)? Or does DA allow the user to provide credentials just like VPN does when setting up DA?

Answer 1

"DirectAccess clients must be members of an Active Directory domain."
