IAM role
An AWS identity with a set of permissions that people or services take on temporarily, rather than a user with permanent passwords or keys. A third party is usually given access to an AWS account by being allowed to assume a role there. Why it matters: The role's permissions are the hard limit on what any connected cost tool can see or change.
