Proxy Authentication for Beginners: Password or Whitelist?
First, the jargon: authentication just means proving to the proxy that you're a paying customer before it carries your traffic. There are two standard ways to do it. One is a username and password. The other is an Liste blanche d'adresses IP: you register your own IP addresses, and the proxy lets those straight in. Both are secure, both come with every plan we sell, and neither is better for everybody.
Pick yours with three quick questions:
- Do you use a laptop, or move between networks? Choose username and password.
- Does everything run from one computer or server whose IP never changes? The whitelist will be tidier.
- Still unsure? Start with username and password. You can switch in the dashboard at any time.
Setting up for the very first time? Keep how to use a proxy open alongside this guide. Is this allowed? Whatever you connect to, stick to legitimate tasks and each site's terms of service.

Option 1: a username and password, like a key you carry
With this method, every request carries your username and password, and the gateway checks them before letting the request through. Usually they go straight into the proxy address, in the form http://USER:PASS@HOST:PORT, or you type them when your browser pops up a login box.
The big plus is that a key works wherever you take it. Your laptop in a café, your desktop at home and a cloud server can all use the very same login, on any network. The catch is just as simple: anyone who gets hold of your login can use your proxy, and your data allowance with it, so keep it to yourself.
Option 2: an IP whitelist, like your name on a guest list
With IP whitelisting, which you'll also see called IP authentication, you tell your dashboard which IP addresses are allowed to use your proxy. Requests from those addresses walk straight in with no username or password at all, and anything from an address that isn't on the list is turned away at the door.
That's neat for a machine whose IP never changes, such as a server, because there's no password to store or swap. The catch is that it only works from addresses on the list. Home broadband and mobile data often change your IP, and when that happens you'll need to update the list before the proxy lets you in again.
Which should you pick? The trade-offs side by side
The table sums up the trade-offs. If you remember only one thing, make it this: a username and password suit you if you move between networks, and a whitelist suits you if everything runs from one fixed server.
| What to compare | Username & password | Liste blanche d'adresses IP |
|---|---|---|
| Where it works | Any device, any network | Only from IPs you have listed |
| What you enter | A login inside the proxy address | Nothing |
| Good for | Laptops that move between networks | A server whose IP never changes |
| What can go wrong | Someone else gets your login | Your IP changes and the list is out of date |
| Available here? | Yes, on every plan | Yes, on every plan |
Four habits that keep your proxy login safe
Whichever method you choose, these habits protect your account and your data allowance:
- Treat the login like any other password. Password managers and environment variables (settings stored outside your code) are good homes for it; code you share with other people is not.
- Keep the whitelist short. List only the IPs you actually use, and delete old ones when you stop using them.
- Don't assume the proxy encrypts everything. It doesn't. Visit sites over HTTPS so your data is protected on the way, because SOCKS5 and plain HTTP don't encrypt anything themselves. Proxy protocols explained covers why.
- Act quickly on a leak. If you think your login has got out, change it straight away rather than waiting to be sure.
