You’d use AWS Organizations so each admin authenticates using their own credentials, gets short-term credentials to access the member account for the handful of operations needing root, and audit usage. It’s not only more secure, it’s also easier:
https://docs.aws.amazon.com/IAM/latest/UserGuide/id_root-ena...
Old school, you’d have a shared password in an encrypted team vault (possibly requiring x of y users to decrypt it) and two FIDO tokens locked in a safe. Again, this is rare and at a federal agency you have a physical security team with 24x7 staffing so you can say “in an emergency, one of the people on this list can get a key out of a safe in the CIO’s office”.
This is a tip of ice-berg, companies like openai, anthropic, perplexity, stripe, all of them have implemented their authentication and security flows in some interpreted language (python, ruby, typescript) cause that was the readily available talent on their product teams and most likely a good number of them do not even have their dependencies locked in.
But, requiring AWS root credentials itself is an anti-pattern and implies an immature organization. That should not be needed for day-to-day operation.
This is all just ignorance and incompetence, nothing more.
> Lastly IT teams in large corporations being secure is a myth for most part.
This is CISA. The Cybersecurity and Infrastructure Security Agency for the United States. Security is what they're supposed to specialize in.
The only potential excuse here is that DOGE gutted them to a point that has completely compromised their capabilities. However, this situation is bad enough that it suggests that problems predated that incident.
Bottomline, you can have any number of boxes to lock other boxes and put their key to bounding box, ultimately there would be one outermost box that is locked by key which is not in any box
Considering thats not the case, what you just did is move the goal post to a account recovery process. Question becomes who has ability to recover the account, in case its tied with email then most likely it has to be a shared email box. What you have now is a much more fragile system in case of custom domains, where whoever is controlling the email domain (DNS management capability) can take over the AWS accounts.
An email per account where only security team has access. Whoever can modify domain can already do this.
