Generate SAML 2 response that Authentication.Failed

Using OKTA to simulate a SAML response to my application they status is always Success.
How can I simulate a SAML2 Response that is not Success i.e, one that is Saml2StatusCodes.AuthFailed ?

Is it possible to generate an Access_token from OKTA ?

SAML doesn’t have access tokens, so not sure what you’re trying to do here if you need to get an access token back…

Yes you are correct, SAML does not have access tokens.

What I was looking for was a way to simulate a failed Assertion from OKTA

Any updates for this question? Is it possible for the SP to obtain a SAML assertion from Okta on failed user authentication? Thanks.
