The AWS codecommit pricing determine a valid user by any unique access identities.
Q: What is the definition of an active user in AWS CodeCommit?
An active user is any unique AWS identity (IAM user/role, federated user, or root account) that accesses AWS CodeCommit repositories during the month, either through Git requests or by using the AWS Management Console. A server accessing CodeCommit using a unique AWS identity counts as an active user.
I created a repo from web console with my AWS root account. For my desktop I create an IAM user with Access Key ID A, and for my Macbook Pro, I add second Access Key ID for the same IAM user.
Then I saw its counted as 3 user access, charged with $1 USD x 3 / per month for the repo... lol
