A session can be created using CredSSP as the authentication provider:
New-PSSession -ComputerName PSTest -Credential (Get-Credential) -Authentication CredSSP
CredSSP must be enabled on the client to support passing credentials to a remote system. The DelegateComputer parameter can be used with either a specific name, or with a wildcard (*):
Enable-WSManCredSSP -Role Client -DelegateComputer PSTest
CredSSP must also be enabled on the server to receive credentials:
Enable-WSManCredSSP -Role Server
If this approach is used as a temporary measure, the CredSSP roles might be removed afterward.
On the server making the connection, the Client role can be disabled:
Disable-WSManCredSSP -Role Client
On the remote system, the Server role can be disabled:
Disable-WSManCredSSP -Role Server
