No, the AliExpress account will not automatically become the same as the Taobao account after logging into the Taobao account. Taobao and AliExpress are two independent platforms under Alibaba. Although you can use the Taobao account to log in to AliExpress, the accounts are still separate and have different settings and functions. Taobao accounts are mainly used for shopping in China, while AliExpress accounts are aimed at the international market and are used for cross-border e-commerce trade. Therefore, logging into the Taobao account will not affect the personalized settings and user experience of the AliExpress account.
