We use two types of Authentication.
1) Username and Password
This authentication uses your Username and API Key as the password
NOTE: The username and API keys are also used in authenticating through terminal commands and language scripts or some other software you use to access proxies that allow for this authentication type:
CMD Terminal Window
2) IP Whitelisting
You can learn more about authentication and whitelisting IPs in our very own Getting Started resource. Allow up to 5 minutes for IP addresses to be whitelisted in our system.
