This topic describes how to obtain an AccessKey pair for your Alibaba Cloud account and Resource Access Management (RAM) user. When you call the Alibaba Cloud Short Message Service (SMS) API, you must use the AccessKey pair to complete 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 a user.
  • The AccessKey secret is used to encrypt and verify the signature string for identity authentication. You must keep your AccessKey secret confidential.
Warning If the AccessKey pair of your Alibaba Cloud account is disclosed, your resources are at risk. We recommend that you call API operations as a RAM user. This minimizes the possibility of disclosing the AccessKey pair of your Alibaba Cloud account.
