I'm a contract web developer, and my client doesn't know anything about managing AWS, but wants to control the billing for the account. So, he wants to give me full access to set up EC2, S3, SES,and RDS.
I told him to create an IAM role for me (IAM > Create Role > Another AWS Account), and I told him which permissions to grant, but from there I'm not sure how to switch to that role.
Is there something else he needs to do to give me access?
