How does a new developer login

The mere fact that I got completely confused trying to create a new (free) developer account for the service that offers identity management service (Okta) is rather funny. Here is what I did so far:

Visited the page at https://developer.okta.com/ and clicked on the “CREATE FREE ACCOUNT” button. Then I provided the information requested by the form at https://developer.okta.com/signup/. As a result I was assigned rather weird “identifier” Okta URL: dev-944584.oktapreview.com, which seems to be the admin ID for my future needs.

Since I provided the name congral as my company name, it seems that I need to login at https://congral.okta.com/. This is where I am confused, as no matter what I try to use as my id (username or email address) followed by my previously defined password, I am denied access. Attempts to reset the password via email, also fail as I never get the email to the address I initially provided.

Can anyone please bail me out? As you can see I was able to get the access to this forum without a hitch, so something ought to be different in the process of getting Okta developer account.
