是否必须使用两步验证？

是的，访问卖家平台的所有用户在登录时都必须启用两步验证，才能访问其卖家平台账户登录。卖家支持员工无法针对此要求豁免任何卖家。

什么是身份验证器应用，可从何处获得？

身份验证器应用是一种独立的软件应用，可下载到智能手机、移动设备（平板电脑、iPad 等）或台式电脑上。它会生成一个可用于两步验证的随机代码。身份验证器应用无法获取您的亚马逊登录凭证。

对于其他接收验证码的方式，我们建议您使用身份验证器应用，因为生成验证码不需要网络连接。如果您在休假或处于其他无法接收短信或语音电话的情况，那么它将是很好的解决方案。

大多数智能手机、移动设备和个人电脑上均提供身份验证器应用，只需在以下应用商店搜索“身份验证器应用”即可：

此外，您会发现可供出售或下载的身份验证器应用类型繁多，包括基于浏览器的扩展程序或插件、桌面应用和基于 USB 的身份验证设备。

有关更多信息，请参阅使用身份验证器应用进行两步验证。

为什么我不能通过电子邮件接收我的两步验证码？

身份验证器应用、短信和电话通常比电子邮件更安全。由于越来越多的电子邮件账户被盗用，亚马逊已选择为卖家提供更高级别的保护。我们不支持使用电子邮件发送两步验证码。

两步验证流程会要求您输入您的密码，以及从您可物理访问的设备获取的随机码。如果通过电子邮件发送验证码，则可以远程访问验证码，这会绕过第二步验证的安全保障。

如果有多个用户使用我的卖家账户，两步验证将如何发挥作用？

由于两步验证关乎着访问账户的个人能否登录，只要访问账户的每个用户都拥有自己的用户账户/登录凭证，就不会对您的账户造成影响。如果有多个用户使用相同的登录凭证访问您的卖家账户，亚马逊建议您为访问您账户的每个用户设置唯一的用户登录凭证。

将登录凭证与多人共享会造成以下问题：

1. 可能存在安全风险。如果有人离开了您的公司/组织并拥有您的登录凭证，他们可能会访问您的卖家账户及关联的买家账户，包括可用的任何信用卡或个人信息。
2. 需要所有用户对所有设备拥有同等的访问权限。如果无法联系到为您的卖家账户设置两步验证的人，则访问该账户的每个用户都需要使用接收验证码的主要和备用方法。否则，在该用户返回之前，该账户的所有工作都需要停止。

如果有多位用户共用卖家平台的相同用户 ID 和密码，我们建议您为每位用户设置次级用户权限。有关如何操作的更多信息，请参阅设置用户权限。设置好次级用户权限后，这些用户将需要在其首次登录时设置两步验证功能。

两步验证是否会影响我的亚马逊买家账户？

是的。当访问您卖家平台账户的用户登录时，系统会应用两步验证。如果您访问您的买家账户时使用相同的登录凭证，那么您在登录亚马逊自营网站时将需要输入您的两步验证码。如果您不想在买家账户中启用两步验证，则可开设一个单独的亚马逊账户来购买商品。但是，我们建议您为所有账户使用两步验证，因为此功能有助于防止账户遭到未经授权的访问。

启用两步验证是否会影响我的第三方连接？ （例如，屏幕截取器、集成器，或数据聚合器。）

如果第三方使用屏幕截取技术通过用户名和密码登录您的账户，那么两步验证可能会影响他们的一些连接。我们鼓励您探索卖家平台中的商城网络服务 (MWS) 或报告是否可提供您使用第三方所获得的功能。

Two-Step Verification FAQ

Is Two-Step Verification required?

Yes, all users accessing Seller Central must have Two-Step Verification enabled on their login to access their Seller Central account. Seller Support Associates do not have the ability to make exceptions for any seller for this requirement.

Can I disable Two-Step Verification?

While it is possible to disable Two-Step Verification via your Advanced Security Settings page, you will be unable to log in to Seller Central until you re-enable it.

All users accessing Seller Central must have Two-Step Verification enabled on their login.

What is an authenticator app and where do I get one?

An authenticator app is a standalone software application that can be downloaded to a smartphone, mobile device (tablet, iPad, etc.), or your desktop computer. It generates a random code that can be used for Two-Step Verification. Authenticator apps do not have access to your Amazon login.

We recommend authenticator apps over other methods for receiving codes because there is no Internet connection required to generate the code. This makes them a great solution if you're on vacation or any other situation where you are unable to receive text messages or voice calls.

Authenticator apps are available on most smart phones, mobile devices, and personal computers – just search for "authenticator app" in the following app stores:

Apple App Store

Google Play Store

Windows Store

 

Additionally, you can find a number of different types of authenticator apps available for sale or download, including browser-based extension or add-ons, desktop applications, and USB-based authentication devices.

For more information, see Use an authenticator app for Two-Step Verification.

Why can't I receive my Two-Step Verification code via email?

Authenticator apps, SMS text, and phone calls are typically more secure methods than email. Due to the increasing number of cases where email accounts are compromised, Amazon has chosen to provide a higher level of protection for sellers. We do not support the use of email for sending Two-Step Verification codes.

The Two-Step Verification process requires you to enter your password, as well as a random code obtained from a device you have physical access to. If the code is sent through email, it can be accessed remotely, which bypasses the security benefit of the second step of verification.

How does Two-Step Verification work if multiple users access my seller account?

Since Two-Step Verification is tied to the login of the individual accessing the account, there should be no impact to your account as long as everyone accessing it has their own user account/login. If you have multiple people who access your selling account using the same login credentials, Amazon recommends that you set up a unique user login for each person accessing your account.

Sharing login credentials with multiple people creates the following problems:

1. Can create a security risk. If somebody leaves your organization with your login credentials, they would have access to your Selling account and the associated buying account, including any credit card or personal information available there.
2. Requires all users to have equal access to all devices. If the person who set up Two-Step Verification for your seller account isn't reachable, everyone who accesses the account would need to have access to both the primary and backup methods for receiving your code. Otherwise, all work on the account would need to stop until that person returns.

 

If you have multiple users who share the same user ID and password for Seller Central, we recommend setting up each user with secondary user permissions. For more information on how to do this, see Set user permissions. Once the secondary user permissions have been set up, these users will need to setup Two-Step Verification on their first login.

Will Two-Step Verification affect my Amazon buyer account?

Yes. Two-Step Verification is applied to the login of the user accessing your Seller Central account. If you use the same login to access the buyer account, you will be required to enter your Two-Step Verification code when you log into the Amazon retail site. If you don't want to have Two-Step Verification on the buyer account, you can open a separate Amazon account for buying. However, we recommend using Two-Step Verification on all of your accounts because it can help protect them from unauthorized access.

Will enabling Two-Step Verification affect my third-party connections? (For example, screen scrapers, integrators, or data aggregators.)

Two-step verification might affect some connections from third parties using screen-scraping technology to sign in to your account via a username and password. We encourage you to explore whether Marketplace Web Service (MWS) or Reports in Seller Central can provide the functionality for which you use a third party.
