Yes. Super VPN mainly works in the browser environment and does not route all system traffic like the latest app.

If the Chrome extension asks for username and password again after you select a server, do not enter your normal app login password directly.

In this case, you should usually enter your compatibility password to verify the server again.

Recommended steps:

1. Enter your account username first.
2. If the popup is a server verification window, enter your compatibility password.
3. After verification succeeds, the extension will usually continue the connection.

Why does this happen?

The old Chrome extension workflow relied on older extension network APIs to handle authentication and request interception. In newer Chrome versions, extension permissions and interception behavior have changed, so the old method may no longer complete authentication automatically in some cases. That is why a verification popup may appear and require manual confirmation.

According to Chrome's official documentation:

• In Manifest V3, webRequestBlocking is no longer available to most extensions: Chrome webRequest API
• Chrome's migration guide also explains that blocking request listeners should be replaced with the newer declarative model: Replace blocking web request listeners
• Authentication handling (onAuthRequired) also depends on related extension permissions: Handling authentication

Please note:

• This browser extension method is only a legacy compatibility solution and is not recommended as your main long-term setup.
• For better stability, we recommend using the latest 5UF VPN app.
• If the verification popup keeps appearing, make sure you are entering the compatibility password, not your normal app login password.
