How Linkage Happens
- If you create an AWS account with email address xyz123@cornell.edu, and there is no existing Amazon.com account for xyz123@cornell.edu then functionally, an Amazon.com account is created for xyz123@cornell.edu and those two accounts (AWS and Amazon.com) are linked forever.
- If you create an AWS account with email address xyz123@cornell.edu, and there already is an existing Amazon.com account for xyz123@cornell.edu, then the two accounts will be linked forever.
Ramifications
In this situation:
- If you were to change the root email address for the AWS account, it would also change the email address for the Amazon.com account.
- If you were to change the email address for the Amazon.com account, it would also change the root email address for the AWS account.
- AWS/Amazon cannot manually unlink or decouple these accounts.
- If the Amazon.com account is closed, the AWS account will remain active.
- If the AWS account is closed, the Amazon.com account remains active.
