Centos Instance: Root & Centos user password

Question

I launched a CentOS 7 1901-01 Lightsail instance and I am wondering about a few things.  
  
If I try to use su - to become the root user, it asks me for my password (for the default Centos user).  
I don't know what that password is. Is there one actually?  
  
Second, is the root user enabled and does it have a password? Do I really need to use it, as I can always use the sudo?  
  
Creating a new user for me from scratch - adding it to the wheel group - and stop using or removing the default Centos user, would that make sense?

Answer

Try using 'sudo su -' instead.  
  
I just spun up a Centos instance and was able to do 'sudo su -' to switch to the root user without needing a password.

Answer

that worked for me too -thanks!
