Two Ways to Authenticate Proxies

Proxy providers offer two main authentication methods:

  1. IP Whitelisting - Your IP address is pre-approved
  2. Username/Password - Credentials authenticate each request

IP Whitelisting

How it works:

  • You provide your server/device IP
  • Provider adds it to an approved list
  • All requests from that IP are allowed

Pros:

  • Simpler setup in many tools
  • No credentials to manage
  • Works with tools that don't support auth

Cons:

  • Tied to specific IP (problematic if it changes)
  • Can't use from multiple locations easily
  • Need to update when your IP changes

Username/Password Authentication

How it works:

  • Provider gives you credentials
  • Include credentials with each proxy request
  • Works from any location

Pros:

  • Works from anywhere
  • Easy to rotate credentials
  • More flexible for distributed setups

Cons:

  • Some tools handle auth poorly
  • Credentials can be exposed in logs
  • Slightly more complex setup
