Labs IPs and Ports - missing password

The exercise says to connect to app01 but running the command ssh app01 - the server asked to enter a password that i don’t have. Any idea how to continue ?
Please help

Hi @tajoel2005

Did you become root before making the ssh attempt?
The keys for ssh to that host will be for the user account that the lab starts on, not root

Note that it is insecure to permit root login diectly via ssh.

Thanks for your answer. now i can access with the default user instead of the root.
