Private proxies are a way to secure your safety and anonymity on the web. However, they’re also not bullet-proof to security issues. Even though you bought a private proxy, you need to protect it to make sure that you are the only one using it. This is why you should make sure to find a private proxy provider that offers an authentication system for its proxies.
Two most common ways of proxy authentication are:
IP Authentication
While they both increase your security, the jury is still out on which method is better. Both systems have their pros and cons, which is why we compared them and tried to help you determine the perfect system for your needs.
This is the most frequently used authentication method around the web. We use username and password for various account types, including e-mail, social media and bank accounts as per law firms. Internet users across the globe accepted this method as a good way of authorizing access to their accounts, so it doesn’t come as a surprise that they are also commonly used when it comes to proxies.
Once you purchase a proxy from a provider, they will send you a list of IP addresses that will look something like this:
123. 456. 7. 890:80:username:password
Let’s break it down to make it clear:
“456. 890” – the IP address of your private proxy
“80” – the port number of your proxy. Other common port numbers include 3127, 3128 and 8080
“username” – your username
“password” – your password. When you choose a password, make sure to make it as strong as possible. A good way to strengthen your password is to use both lowercase and uppercase letters and add numbers and symbols
The list of IP addresses will be different for each proxy you purchased, but other data is often the same. This simplifies the process as you can use the same username and password to connect to all proxies that you bought.
Most providers allow users to change the passwords for their proxies. For security reasons, you may want to change your password frequently. Also, you may want to use a different password for each IP address to increase the security of your proxies.
Providers will usually have a web-based interface allowing you to modify your proxy settings. Once again, you will need to use your username and password to sign in (they might be different than the ones used for proxies). Once you successfully log in, you will have a control panel where you can change your password and take a look at other settings, including the status of your proxies, your subscription plan and so on.
The familiar concept of using usernames and passwords might be the biggest advantage of this system. We all feel comfortable using passwords, which makes this way of authorizing access perfect for beginners.
Another advantage is the fact that you have complete control over your proxy access. You can change the password as frequently as you want and you can use different passwords for each IP address. If you are worried about someone hacking your proxy, changing the password is the perfect way to protect it.
Finally, having a username and password for your proxy means that you can access if from anywhere. That makes this authentication perfect if you travel often or change locations from which you use your proxies.
Having a password also means you have to remember it. Different passwords for different IP addresses also means a bigger number of passwords to remember,  Firewall
