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.
您可以将其他邮箱地址绑定到给自己的 itch.io 账号绑定额外的邮箱，以访问在通过这些邮箱地址下购买的内容。例如，如果您的 PayPal 邮箱地址可能与主邮箱地址不同，因此您可能想将其那么可以考虑将前者添加为附加额外邮箱。
一个额外的账号安全层，有助于防止外人使用您的密码进行未经授权的访问为账号增设的安全防护层，以防密码泄露时他人侵入您的账号。
