How proxy authentication works

Proxy authentication is a challenge–response exchange. Over HTTP it looks like this: your client sends a request, the proxy answers with 407 Proxy Authentication Required, and the client retries with a Proxy-Authorization header carrying login:password in Base64. That's encoding, not encryption — on an unencrypted hop anyone in the path can read the credentials back out. If that hop matters in your setup, the TLS connection to the proxy closes it.

SOCKS5 does it differently: the credentials are negotiated inside the connection handshake (RFC 1929), before any application data flows. Either way, a SOCKS5 proxy with username and password gives you access that travels with the user, not the machine — unlike a whitelist rule, credentials aren't tied to your source address. That's why we issue them together with mandatory IP whitelisting, never instead of it: a leaked password is useless without a whitelisted IP, and a stranger behind your NAT can't get through without the credentials.

Buy a proxy server with a username and password when the whitelist alone is inconvenient: home internet with a changing IP, work from several locations, tools with mandatory login fields, shared team access. The login:password@ip:port format works everywhere — from curl to antidetect browsers. Specs are in the adjacent panel; pricing is in the calculator above.

Which proxies should you choose?

Three access-control setups — and how they differ in security and convenience.

IP whitelisting + credentials
Who can use the proxy Anyonethe proxy is open to the whole internet Only requests from your IPs Requests from approved source IPs with valid credentials
Security Lowanyone who knows the proxy address can use it Highaccess is restricted to approved source IPs Highestboth the source IP and credentials are checked

At PapaProxy.net, IP whitelisting is required for every proxy. Username/password authentication is optional and adds a second access-control layer.

# HTTP or HTTPS proxy
curl -x http://login:password@IP:port https://example.com

# SOCKS5
curl --socks5-hostname IP:port \
  --proxy-user login:password \
  https://example.com
import requests

proxy = "http://login:password@IP:port"  # your proxy from the Dashboard

r = requests.get(
    "https://example.com",
    proxies={"http": proxy, "https": proxy},
)
print(r.status_code)
import { ProxyAgent } from "undici";

const dispatcher = new ProxyAgent("http://login:password@IP:port");
const res = await fetch("https://example.com", { dispatcher });
console.log(res.status);
$ch = curl_init("https://example.com");
curl_setopt($ch, CURLOPT_PROXY, "IP:port");
curl_setopt($ch, CURLOPT_PROXYUSERPWD, "login:password");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
Fill in the credentials from your Dashboard. If you use IP whitelisting, you don't need a username or password.

Хорошая скорость, доходит до 1Гбит/с. Прокси поддерживают многопоток. На один адрес по 1 млн одновременных запросов выдерживают. Пытался положить сервер – не выходит. Качественные прокси, рекомендую.

A Albert September 2024

For the third time I renewed my subscription, there were no crashes. Not a single account has crashed, which means that the proxy works very well. I advise to use them.

AS Aiden Symon December 2025

I have no complaints about the service. I have bought more than a dozen proxies, all work, the speed is acceptable. In 3 months of use nothing flies off, speeds do not drop. Admins respect. If you are looking for a reliable solution, consider their new fast private socks proxy service provider for top-tier performance and reliability.

S Stephen June 2026

The main thing is to check their proxy list and make sure it is up-to-date and in good condition.

Frequently asked questions

Can I use a username and password instead of IP whitelisting? I do not have a static IP.

Not instead — only together: IP whitelisting is required on every plan. A changing IP does not block you: update your whitelist in the Dashboard or via the API. Your ISP assigns a new address — one API call restores access; you can automate that with a script on your router or server. More on using our proxies with a dynamic IP.

Why do I need a password if IP whitelisting already limits access to me?

Because an IP is a network address, not a personal key. Every device behind your home router looks the same to the proxy, as do all colleagues behind office NAT. A password narrows access: not «anyone on your IP,» but whoever knows the credentials. It also helps if your ISP reassigns your old IP to another customer while your whitelist entry still points at it.

My HTTP proxy with authentication returns 407 even though the password is correct. What now?

Check the special characters first. In the inline login:password@ip:port format, the characters @, :, and % are separators — a password containing @ splits the URL in the wrong place, and the proxy receives garbage instead of your credentials. Two fixes: percent-encode the character (@ becomes %40), or skip inline entirely and pass credentials through a dedicated option — curl has --proxy-user, most libraries have separate username/password fields that take the raw string. On our plans there's a second thing to verify: credentials work alongside the whitelist, so if your source IP isn't added in the Dashboard, no password will get you through.

How do I share one plan across a three-person team?

Whitelist every work location — up to five slots included — and share the proxy server login through a password manager, not as plain text in a messaging app. A proxy with username/password authentication does not tell who connected, so split package IPs between people upfront: two people on one IP hitting the same target site is an easy path to bans.

Where should I put credentials in scraper code so they do not leak?

Not in source code. Store the username and password in environment variables or a .env file listed in .gitignore; the script should only read them at runtime. Leaked proxy credentials in a public repository are common — bots scan GitHub faster than most teams notice an accidental push. Even leaked credentials will not work without a whitelisted source IP on our end — but you should not rely on testing that.
