no access to the root

Root access is not active, someone has been able to enter?
Access gives you is for the user "centos" then with the command "su" to "root" for a password.
The documentation says "This image is built to allow remote ssh login only as 'root' user With the key specified at launch time instance" but at no time asked me a key.
Someone could solve this?
Thank you
