Using this parameter you can override the authentication used to connect to the selected remote Jenkins.

• Don't Override
  The authentication configured in the (global) settings of the selected 'remote host' is used.
• Token Authentication
  The specified user id and Jenkins API token is used.
• Credentials Authentication
  The specified Jenkins Credentials are used. This can be either user/password or user/API Token.
• No Authentication
  No Authorization header will be sent, independent of the global 'remote host' settings.

Note: Jenkins API Tokens are recommended since, if stolen, they allow access only to a specific Jenkins while user and password typically provide access to many systems.
