When you sign up for Amazon Web Services (AWS), your AWS account is automatically signed up for all services in AWS. You are charged only for the services that you use.

If you already have an AWS account, skip to the next task. If you don’t have an AWS account, follow these steps to create one.

To create an AWS account

Open https://portal.aws.amazon.com/billing/signup .

Follow the online instructions.

Part of the sign-up procedure involves receiving a phone call and entering a verification code on the phone keypad.

When you sign up for an AWS account, an AWS account root user is created. The root user has access to all AWS services and resources in the account. As a security best practice, assign administrative access to an administrative user, and use only the root user to perform tasks that require root user access.

Configure the admin iam user using the command below.

aws configure --profile admin

This profile has a max-out permission level within your AWS account. We’ll use this profile only for the configuration of new policies and creating new users. After that, we’ll use a more restricted IAM user.
