AWS Certified Solutions Architect Associate SAA-C03 Practice Question

Enabling multi-factor authentication (MFA) on the root user account is a recommended AWS security best practice. MFA adds an extra layer of protection on top of the username and password, making it significantly harder for unauthorized users to gain access. Sharing the root user credentials with others is not recommended, as the root account has unrestricted access to all resources. Using the root account for daily operations is discouraged; instead, you should create IAM users and roles with appropriate permissions. Additionally, you cannot create multiple root user accounts; each AWS account has a single root user.
