Taobao has two registration methods: mobile number registration and email registration. No matter which registration method you choose, you must not check the "Create Alipay account with this mobile phone (email)" in the following figure. This is because you already have an Alipay account, so you can only register one Taobao account,After registration, log in to Taobao - My Taobao - Alipay Account Management, where you can buy things on Taobao with 200 Alipay accounts tied to your Taobao account, and pay automatically with your Alipay account.
Hey hey, the email you use when you register your Taobao account is your Alipay account. By default, when you register Taobao, you also register Alipay.You can go to the top right corner of Taobao official website to register for free.
