c# Open Default browser with a link and wait for a response

The problem is I will open a link(facebook login) and wait for the user to login then get whats written after. The link will be open by c# desktop app/WinForms

I have done what I want to achieve using webbrowser but the user will login again on facebook even though they are logged in already (example in chrome).

When I'm installing adobe photoshop I have seen this feature.

Thank you very much in advance.
