Link or unlink a third-party account
This topic describes how to link your third-party accounts, such as Alipay, Taobao, 1688, and Weibo, to your Alibaba Cloud account. Linking a third-party account lets you log on to and manage Alibaba Cloud services without having to remember a separate username and password.
Prerequisites
A valid Alibaba Cloud account is required. If you do not have an account, register one on the official Alibaba Cloud website. For more information, see Register an account (PC).
You must have at least one third-party platform account, such as Alipay, Taobao, 1688, or Weibo.
Link a third-party account
Log on to the Alibaba Cloud Account Center. In the navigation pane on the left, choose My Account > Account Security.
In the Logon Method section, find Third-Party Logon and click Settings.
On the Third-Party Logon Settings page, select the third-party account that you want to link and click Link Now. This topic uses Alipay as an example.
On the third-party account linking page, read and agree to the third-party account linking logon protocol. Then, click Confirm Link.
On the identity verification page, select a method to complete the identity verification. This step ensures the security of the linking procedure.
After you complete the identity verification, follow the prompts to log on to your Alipay account.

After you log on, the Alipay account is linked. Return to the Alibaba Cloud Account Security page to view the linked third-party account and confirm its status.
