IAM Authentication

IAM authentication in AWS includes the following identities:

• Users
• Groups
• Roles
• Temporary security credentials
• Account root user

Identities are used to provide authentication for people, applications, resources, services, and processes in your AWS account. Identities represent the user that interacts with the AWS resources based on authentication and authorization to perform various actions and tasks. We will look at each one of the identities in detail.
