[Feature]: BasicAuthenticationRequested event and passing the current user credentials

[sergiocapozzi77]

Describe the feature/enhancement you need

Hi,

I'm working with an internal website that requires authentication via a token obtained through a web request using credentials (withCredentials: true). When accessing this site in Chrome or Edge, the authentication happens seamlessly without any prompts.

However, when accessing the same site through WebView2, a login prompt appears requesting credentials. I also noticed that the BasicAuthenticationRequested event is triggered.

Is there a way to configure WebView2 to automatically use the current user's credentials, similar to how it works in standard browsers?

I’ve already set AllowSingleSignOnUsingOSPrimaryAccount = true, but that doesn’t seem to make a difference.

Interestingly, on my PC the site loads without any login prompt, but on every other machine tested, the login prompt consistently appears.

The scenario/use case where you would use this feature

HAving the login prompt poppping all the time is quite annoying for the users

@sivMSFT thanks for the response, but I have added:
AdditionalBrowserArguments = "--msSingleSignOnForInPrivateWebView2 --msAllowAmbientAuthInPrivateWebView2"

But the login popup is still appearing
