Trigger okta when we have multiple stand alone Identity providers using HttpContext.GetOwinContext().Authentication.Challenge()

Hi, I can trigger Microsoft, facebook, google by providing name of the provider as parameter to HttpContext.GetOwinContext().Authentication.Challenge(providerName). Now I added octa and want to trigger it so it will redirect the caller to it’s authentication page and gives me accesss token. How to achieve this in .net framework 4.6. Please help!.

Are you trying to use Okta like a Social auth provider? Does your .NET application currently only work for these social providers and you haven’t yet integrated with Okta?

Yes, I am using it as an additional identity provider.
I am new to okta and trying to use okta without changing current implementation.
