Where does the owner *name* for an S3 bucket/AWS account come from?

Question

This feels like it should be really obvious, but I can't find any clues. I've just started using S3 on AWS. I set up a new free account linked with my Amazon account. When I create a bucket, the name of the owner of the bucket is different from my IAM name, from my AWS account name, and from my Amazon account name. Where does that owner name come from? How can I change/edit it?

Answer 1

S3 actually uses AWS root account user's forum account's nickname in the Owner and Grantee fields. There is a discussion about this here.

You can change the forum nickname, in order to change what is displayed in S3, here.

Answer 2

AWS is stupid here. According to AWS support, it is your root account's forum account's initial nickname. However it is there forever, even later you change your forum account's nickname. AWS is not able to change it.
