Instead of sharing the credentials of the AWS account root user, create individual IAM users, granting each user only the permissions they require.

Follow the best practice of using the root user only to create your first IAM user.

There are two types of credentials:

• Root user credentials, allow full access to all resources in the AWS account.
• IAM credentials, control access to AWS services and resources for users in your AWS account
