This topic describes how to create an AccessKey pair for an Alibaba Cloud account or a RAM user. When you call an API operation of Short Message Service (SMS), the AccessKey pair is required for identity verification.

Background information

An AccessKey pair consists of an AccessKey ID and an AccessKey secret.

  • The AccessKey ID is used to verify the identity of the user.
  • The AccessKey secret is used to encrypt and verify the signature string for identity authentication. You must keep your AccessKey secret strictly confidential.
Warning If the AccessKey pair of your Alibaba Cloud account is disclosed, your resources are exposed to potential risks. We recommend that you use the AccessKey pair of a RAM user to call API operations. This minimizes the risks of disclosing the AccessKey pair of your Alibaba Cloud account.
