An AWS Identity and Access Management (IAM) user is an entity that you create in AWS to represent the person or application that uses it to interact with AWS. A user in AWS consists of a name and credentials. An IAM user with administrator permissions is not the same thing as the AWS account root user.

What is IAM user and root user in AWS?

There are two different types of users in AWS. You are either the account owner (root user) or you are an AWS Identity and Access Management (IAM) user. The root user is created when the AWS account is created. IAM users are created by the root user or an IAM administrator for the account.

What are IAM users and groups?

An IAM user group is a collection of IAM users. User groups let you specify permissions for multiple users, which can make it easier to manage the permissions for those users. For example, you could have a user group called Admins and give that user group typical administrator permissions.

What is the main purpose to have a IAM user?

What is IAM role and policy?

What is more secure IAM user or IAM role?

An employee can assume a role (which is logged in CloudTrail), giving them the permissions of that role for a short time. This enables the user to request short-term credentials from AWS STS, which is more secure than attaching the permissions directly to the user’s access keys.

What is difference between IAM user and role?

An IAM user has permanent long-term credentials and is used to directly interact with AWS services. An IAM role does not have any credentials and cannot make direct requests to AWS services. IAM roles are meant to be assumed by authorized entities, such as IAM users, applications, or an AWS service such as EC2.

What is the difference between a role and a user?

A role typically defines a business function (or set of functions) performed by one or more users. Examples would be ‘customer service agent’ or ‘business analyst’. A user is an individual person who is included in the role – Bob, Nancy, and Steve might be assigned to the customer service agent role.

When should you use AWS IAM roles VS users?

A user is made up of a name, password for the AWS Management Console and access keys to use with the API or CLI. Unlike roles, users are associated with long-term credentials. An IT pro typically chooses to be an IAM user when they create an AWS account and they are the only one that uses it.

What is the difference between roles and permissions in AWS?

AWS Identity and Access Management (IAM) roles provide a way to access AWS by relying on temporary security credentials. Each role has a set of permissions for making AWS service requests, and a role is not associated with a specific user or group.

You can use the AWS Management Console to create a role that an IAM user can assume. For example, assume that your organization has multiple AWS accounts to isolate a development environment from a production environment.

Technically, yes, there is a way to assume multiple IAM roles at the same time. But it doesn’t mean what you intend. Assuming an IAM role doesn’t modify who you are and doesn’t modify what permissions you have — contrary to the intuitive interpretation of what it might mean to assume a different identity.
