A financial company needs to create a separate AWS account for a new digital wallet application. The company uses AWS Organizations to manage its accounts. A solutions architect uses the IAM user Support1 from the management account to create a new member account with finance1@example.com as the email address. What should the solutions architect do to create IAM users in the new member account?

1. Sign in to the AWS Management Console with AWS account root user credentials by using the 64-character password from the initial AWS Organizations email sent to finance1@example.com. Set up the IAM users as required.
2. From the management account, switch roles to assume the OrganizationAccountAccessRole role with the account ID of the new member account. Set up the IAM users as required.
3. Go to the AWS Management Console sign-in page. Choose “Sign in using root account credentials.” Sign in by using the email address finance1@example.com and the management account's root password. Set up the IAM users as required.
4. Go to the AWS Management Console sign-in page. Sign in by using the account ID of the new member account and the Support1 IAM credentials. Set up the IAM users as required.
