Yes. Proxy-Cheap supports IP whitelist authentication for eligible Datacenter IPv4 and Static Residential proxies.

With IP whitelist authentication, only the IP addresses you add to your allowed list can connect through the proxy. You do not need to enter a proxy username and password from a whitelisted IP address.

IP whitelist authentication is not available for Rotating Residential Proxies. Available authentication options can vary by product and network, so check your Proxy-Cheap dashboard for the options available for your proxy.
