Two common authentication methods for private agents

Private proxies can only be used by one person at a time. Scraping is the most common application scenario for private proxies, which can maintain anonymity and avoid being tracked by websites. During the data mining process, private proxies prevent IP addresses from being banned, making the task easier.

Before buying a private proxy, find a private proxy provider that provides an authentication system as part of its private proxy service. There are two common ways of private proxy authentication:

1. Username and password authentication

This method is very common and often used among Internet users. It is also easy because you only need to provide your login details, i.e. username and password.

2. Whitelist IP authentication

When you buy a proxy from a private proxy provider, an IP address is assigned to you. This IP can be used for authentication. This is a simple way to grant you authorized permissions to the proxy. It has its own advantages and disadvantages compared to the username and password method. You must whitelist your IP address with your private proxy provider, which means that you can only access the proxy from that whitelisted IP.
