You can link additional email addresses to your itch.io account in order to get access to anything purchased under those email addresses. For example, your PayPal email address might be different than your regular email address so you'd want to add it as an additional email.
你可以将一个附加邮箱地址绑定到你的itch.io账户，以获得该邮箱地址购买的东西的访问权限。例如，你的PayPal邮箱地址可能与你的常规邮箱地址不同，因此你会想要将其作为附加邮箱添加。
