Registering an Account and Completing Real-Name Authentication

Skip this part if you already have an account of Huawei Cloud and completed real-name authentication. If you do not have an account of Huawei Cloud, perform the following steps to create one:

  1. Visit Huawei Cloud official website, and click Sign In.
  2. Sign up for a HUAWEI ID and enable Huawei Cloud services. After your registration is successful, the system automatically redirects you to your personal information page.
  3. Complete real-name authentication by following the instructions in Individual Real-Name Authentication.

    Real-name authentication is required when your account purchases or uses resources in Chinese mainland regions.

    Real-name authentication is not required when your account purchases or uses resources in regions outside the Chinese mainland.

Topping up Your Account

Ensure that your account balance is sufficient.
