# Set up Amazon SageMaker Ground Truth Plus Prerequisites


The following page describes how to sign up for an Amazon account and configure an administrative user in your account. If you already have an Amazon account and user setup, you can skip this page.

## Sign up for an Amazon Web Services account


If you do not have an Amazon Web Services account, use the following procedure to create one.

**To sign up for Amazon Web Services**

1. Open [http://www.amazonaws.cn/](http://www.amazonaws.cn/) and choose **Sign Up**.

1. Follow the on-screen instructions.

Amazon sends you a confirmation email after the sign-up process is complete. At any time, you can view your current account activity and manage your account by going to [http://www.amazonaws.cn/](http://www.amazonaws.cn/) and choosing **My Account**.

## Secure IAM users


After you sign up for an Amazon Web Services account, safeguard your administrative user by turning on multi-factor authentication (MFA). For instructions, see [Enable a virtual MFA device for an IAM user (console)](https://docs.amazonaws.cn/IAM/latest/UserGuide/id_credentials_mfa_enable_virtual.html#enable-virt-mfa-for-iam-user) in the *IAM User Guide*.

To give other users access to your Amazon Web Services account resources, create IAM users. To secure your IAM users, turn on MFA and only give the IAM users the permissions needed to perform their tasks.

For more information about creating and securing IAM users, see the following topics in the *IAM User Guide*:
