SSH Asking for a password for certain commands

Probably goes without saying, but I am new to DO and everything involved with it.

I was setting up my first server and set up ssh and I can successfully ssh into my server.

Perhaps I don’t yet have a firm enough grasp on SSH, but when executing certain commands, like sudo service fail2ban restart I am asked to input my password.

I was under, maybe the false, impression that when I SSH I wouldn’t need to use my password. Am I incorrect? Is it perfectly normal to be asked for your password to execute certain commands even if you are SSH-ed into the server?

Thanks for the help, I apologize for any terminology misuse.

Hi quoid. What Nixola is saying is that yes, it is normal to have to enter a password every so often when executing commands such as the one you originally mentioned ( sudo service fail2ban restart ) …I think the sudo user password is requested something like every fifteen minutes or so, as well as of course at the start of your session if you are entering a sudo command. How you are doing things is correct, in that you are using a new user with root privileges instead of using root. What Nixola was saying to you when referencing “don’t do this”, was basically saying use a sudo user and not the root account, because it is generally advised to disable the root account login after your new user has been created.
