> In 2025 there's no reason for anyone to be logging into an AWS account via the root credentials and this should have been addressed in the preventative measures.
I am curious what preventative measures you expect in this situation? To my knowledge it is not actually possible to disable the root account. They also had it restricted to only 3 people with MFA which also seems pretty reasonable.
It is not unheard of that there could be a situation where your ability to login through normal means (like lets say it relies on Okta and Okta goes down) and you need to get into the account, root may be your only option in a disaster situation. Given this was specifically for oncall someone having that makes sense.
Not saying there were not failures because there clearly are, but there have been times I have had to use root when I had no other option to get into an account.
