Are you confused with Root User and IAM User in AWS account ?

When you create an AWS account, you get a root user by default. However, AWS strongly recommends not using the root user for daily operations. Instead, you should create IAM users with appropriate permissions.

What is an AWS Root User ?

The root user is the superuser of an AWS account. It is created when you sign up for AWS and has unrestricted access to all AWS services and resources. This user is tied to the email address used during account creation.

Now Lets talk about the Key Features of Root User,

• It has full access to all AWS services and resources.
• Can perform critical actions like changing billing settings, closing the account, and managing IAM policies.
• Cannot be restricted by IAM policies.
• Requires MFA(multi-factor authentication) for added security.

What is an IAM(Identity and Access Management) User ?

IAM users are individual users created within an AWS account. Each IAM user can have specific permissions assigned via IAM policies.

Now Lets talk about the Key Features of IAM User,

• These are users created under an AWS account with specific permissions.
• IAM users can be assigned roles, groups, and policies to restrict or grant access based on need.
• Can be assigned temporary access using IAM roles.
• Can have MFA(multi-factor authentication) enabled for additional security.

Best Practices for Managing Users in AWS

1. Secure the Root User: Enable MFA and use it only for critical tasks.
2. Create IAM Users: Assign permissions based on roles and responsibilities.
3. Use IAM Roles: Instead of sharing credentials, use roles for temporary access.
4. Implement Least Privilege: Grant users only the permissions they need.
5. Monitor and Audit Access: Use AWS CloudTrail to track user activity.

The root user is powerful but should be used sparingly. IAM users allow for controlled access and better security management. Following AWS best practices ensures a secure and well-managed AWS environment.

By understanding and properly configuring AWS user management, you can enhance security and maintain efficient access control within your AWS infrastructure.
