Dump question I guess, but I would like to follow what is said in the security & compliance section. There is a button "follow" that redirects me to a login page. I am supposed to provide credentials to either a "root" account or an "IAM" account. Assuming I have neither, I do not use AWS by myself and just want to take part in the discussion forums, should I create a root account or an IAM account?
