How to use SwitchyOmega with Auth Proxy (2025 Guide)

If you are a developer testing APIs or a QA engineer verifying geo-targeted content, changing your system-wide proxy settings every time is a pain.Proxy SwitchyOmega is the best Chrome extension to manage multiple proxies and switch between them with one click.

In this guide, we will set up a "Chaos Profile" using Debuggo to simulate a slow network connection (3G speed) only for specific tabs.

Step 1: Install the Extension

Go to the Chrome Web Store and install Proxy SwitchyOmega. It works on Chrome, Edge, Brave, and other Chromium-based browsers.

Step 2: Create a New Profile

1. Click the SwitchyOmega icon in your toolbar and select Options.
2. In the left sidebar, click New Profile...
3. Name it Debuggo Chaos and select Proxy Profile. Click Create.

Step 3: Configure Proxy Server

Now, enter your proxy server details. If you don't have one, you can generate a free cloud proxy on Debuggo.

Authentication (Crucial Step)

Most cloud proxies require a username and password. SwitchyOmega handles this differently:

1. Click the Lock Icon 🔒 on the right side of the "Proxy auth" row.
2. Enter your Username and Password provided by Debuggo.
3. Click Save Changes.
4. Finally, click the big green Apply Changes button in the left sidebar.

Step 4: Testing & Troubleshooting

Click the extension icon and select your new Debuggo Chaos profile. The icon should turn colored.

Now visit httpbin.org/ip. You should see the IP address of the proxy server, not your own.

Why use this setup?

• Chaos Engineering: You can now configure Debuggo to return 500 errors or delay responses by 5 seconds, and it will only affect this browser profile.
• Isolation: Your Spotify music streaming in another window won't buffer because it's not using the proxy.
