When an AWS account is created, the root user is automatically created as the first sign-in identity for that account. The root user has full administrative access to all resources and services within the AWS account. However, it is considered a security best practice to not use the root user for everyday tasks and to create additional IAM (Identity and Access Management) users with appropriate permissions.
When you create an AWS account, the first sign-in identity that is created is the root user. The root user has complete access to all AWS services and resources in the account, making it a very powerful account. Therefore, it is best practice to create and use individual IAM (Identity and Access Management) users for day-to-day activities, and only use the root user when absolutely necessary.
The root user is the only user that can perform certain tasks, such as creating and managing IAM users, billing and payment information, and closing an AWS account. However, the root user is not the only user that can access the AWS Management Console. IAM users with the appropriate permissions can also access the console.
It is important to secure the root user account with a strong password and enable multi-factor authentication (MFA) to prevent unauthorized access to the account. Therefore, the root user is not the only user that can be configured with MFA.
C. The root user is the first sign-in identity that is available when an AWS account is created.
Explanation: The AWS account root user is created automatically when the AWS account is created. This user has full access to all AWS services and resources in the account. The root user is the first identity that is available to sign in to the AWS account, and it cannot be deleted. However, it is recommended that the root user not be used for everyday tasks in order to improve security. Multi-factor authentication (MFA) can be configured for the root user, but it is also recommended to create additional IAM users with appropriate permissions for daily operations. The root user can access the AWS Management Console, but other IAM users can also be granted access. The root user's password can be changed for security purposes.
A - I have one IAM user, I am able to use MFS
B - My IAM user is able to access the Console
C - This is true
D - I can change my root user password. In fact, recently I had to change due to a policy change in AWS
C. The root user is the first sign-in identity that is available when an AWS account is created.
The AWS account root user is the initial user identity created when an AWS account is created. It has complete access and control over all resources in the AWS account, and it cannot be deleted. However, it is recommended to create IAM (Identity and Access Management) users and groups and use them instead of the root user to manage AWS resources.
Option A is incorrect because MFA can be enabled for any IAM user, including the root user.
Option B is incorrect because IAM users can also access the AWS Management Console if they have been granted the necessary permissions.
Option D is incorrect because the root user can change its password just like any other IAM user.
