Core Config Manager Login Failed

[xyrus1]

I have deployed Virtual Machine version of Nagios XI and have used almost everything default. I did change the password for nagiosadmin user though.
When I click on "Core Config Manager" under "Admin", It asks for username and password. I have tried nagiosadmin and my current password and it does not work.

Wondering, if anyone is aware which username it would be.

Thanks.

The Core Config Manager requires a separate authorization, which can be specified in the Admin->Reset Security Credentials page.
