Two common authentication methods for private agents - WHOER

Private agents can only be used by one person at a time. Crawlers are the most common use case for private agents, which maintain anonymity and avoid being tracked by websites. During data mining, private agents prevent IP addresses from being banned, thus making the task easier.

Before buying a private agent, find a private agent provider that offers an authentication system as part of their private agent service. There are two common ways of private agent authentication:

1. User name and password authentication

User name and password authentication is a very common authentication method in private agents, which is widely used among Internet users. The advantage of this method of authentication is that it is simple to use, and users can easily access private agents by providing the corresponding login details, that is, a user name and password.

①Use of reverse proxies

In user name and password authentication, each user is assigned a unique user name and password. When using a private agent, users need to enter the correct username and password before using the agent. Only authenticated users are granted access, allowing them to use private agents for surfing and network access.

This authentication method is especially suitable for scenarios that require multiple users to access, such as internal employees or users of shared agents. By assigning each user a different username and password, a private agent can precisely control each user's access rights. Employees within the enterprise can obtain different levels of access depending on their position or needs to ensure the security of sensitive information. Each user of the shared proxy has an independent login certificate, which prevents information communication between users and protects user privacy. In addition, the user name and password authentication method can also track the use of each user, record the user's access history and activity. This can be very useful for businesses or organizations to help them understand the online behavior of employees or users, monitor network usage, and ensure the proper use of network resources.

It should be noted that when using user name and password authentication, users should properly keep their login credentials to ensure that they are not obtained by others. At the same time, private proxy service providers should also take measures to ensure the security of user login information and prevent user information from being leaked or attacked.

2. Whitelist IP authentication

Whitelist IP authentication is a common authentication method in private agents. It provides a simple and effective authentication method for users. When a user purchases an agent from a private agent provider, they are given a specific IP address, which can then be used for authentication.

②How to improve the crawling efficiency

In the whitelist IP authentication mode, users need to whitelist their IP addresses together with their private proxy providers. Only IP addresses in the whitelist are considered legitimate users authorized to access the proxy. In this way, the private agent can precisely control who has access to the proxy service, thus ensuring the security and stability of the proxy service.

Whitelisted IP authentication is applicable to those who have fixed authorized users, such as internal employees, VIP customers, or individual users with customized proxy services. For these users, their IP addresses are fixed and immutable, so whitelisting them is a viable option. This method prevents other unauthorized users from using the agent and increases the security of the agent service. For internal employees, whitelisted IP authentication can also set different levels of access rights according to the positions and needs of employees, ensuring that sensitive information can only be accessed by authorized personnel.

No matter which authentication method is chosen, private agents can provide greater stability, better security, and more flexible access control. Private agents are suitable for those users who need more strict management and control of proxy services, ensuring user privacy and data security. When selecting a private proxy service provider, you are advised to select a trusted service provider to ensure the stability and security of the proxy server, thereby achieving a better proxy experience.
