After login on one website when i browse second site, it does not auto login. After doing some analysis i found .ASPXAUTH cookie is not creating. I am not sure what are the actual cause but at initial stage i found this cookie is missing. What could be the possible reasons on not creating this cookie?

Check the browser configuration first - may be Block third-party cookies is enabled.
If its enabled you can whitelist you okta URLS in exception.
Normally we add two urls there -
https://myorg-admin-okta-emea.com
https://myorg-admin-okta-oktapreview.com
Actually we are doing a upgrade of system from older version to new version in Sitecore 9.3. In older version it works fine with same urls but in new version it does not work.
And in new version i found .ASPXAUTH cookie is missing.
Use some tool like fiddler to see the http request/ response headers and to see whether you are receiving the cookie from the client or not.
any idea what is the name of cookie which Okta returns?
No idea, but first check whether its setting any value in Cookie PARAM or not. Also, let me know if have tried with different-2 browsers or not ?
Is the behavior same with Chrome, Mozilla and IE ??
i have the same behavior on all browsers and it is setting below cookie.
I am not Sitecore expert but a lot of things changed in Sitecore 9.1 onwards like Sitecore 9.1.0 or later does not support the Active Directory module, you should use federated authentication instead.(https://doc.sitecore.com/developers/93/sitecore-experience-manager/en/sitecore-identity.html)
You had upgraded from which version to 9.3 if it before 9 then you may revisit the integration.
I have never done the integration with Sitecore so may be someone else can give you more idea in community.
thanks Saurabh.
