SAP HANA One on AWS - root credentials

I have installed Rev 091.1; based on SAP HANA SPS9 in an AWS instance. This are going well, but I see a highlight saying, "Default 'ec2-user' SSH login: HANA One instances are now more secure with SSH root login disabled. Customers can now login to the instance using the new 'ec2user' user"

Ok, but what will the password be? I see no indication of how to tell

Thanks

Bob
