什么是兩步驗證？

兩步驗證就是您在應用電子郵件地址拜訪賬戶時額外添加的一層安全掩護。登錄賣家平臺時，請先輸入您的尺度登錄名/密碼。然后還有第二個驗證碼，我們通過短信、語音電話或身份驗證器運用發送到您選擇的裝備上。

您須要應用兩步驗證能力拜訪您的賣家平臺賬戶。兩步驗證是防止您的賣家賬戶被盜用的更佳掩護辦法，即使您的密碼被盜，也能供給有力的掩護，尤其是當您在多個網站應用雷同密碼時，這種辦法非常有效。

兩步驗證如何施展作用？

如果拜訪的賬戶在登錄時須要進行兩步驗證，您首先須要正常輸入您的賣家平臺用戶名和密碼。然后，體系會提醒您輸入驗證碼。此代碼將發送至您在設置期間選擇的裝備。如果無法拜訪該裝備，則任何嘗試登錄您賬戶的未授權用戶均將被謝絕拜訪。

兩步驗證對裝備有什么請求？

首次激活兩步驗證時，您須要指定兩個不同的裝備用于吸收驗證碼。一個是您吸收驗證碼的重要方法，另一個是在您無法拜訪主裝備時的備用裝備。

您可以應用以下選項吸收驗證碼： 身份驗證器運用、通過手機或固話進行語音呼喚，或通過短信吸收。我們建議您應用身份驗證器運用，因為其易于應用，無需拜訪網絡，而且隨時可用。此類運用可以通過個人電腦以及智能裝備（包含手機和平板電腦）上的運用商店免費獲得。有關更多信息，請參閱應用身份驗證器運用進行兩步驗證。

您不能將身份驗證器運用同時用作重要辦法和備用辦法。您必需選擇支撐短信或語音功效的電話作為吸收驗證碼的重要或備用方法。下表概述了可供您應用的重要和備用選項：

如果您吸收驗證碼的重要裝備是：	您必需選擇以下任一選項作為您的備用裝備：
開通短信支撐的電話（用于吸收短信）	支撐語音功效的其它電話* 開通短信支撐的其它電話* 身份驗證器運用
支撐語音功效的電話（固定電話）	支撐語音功效的其它電話* 開通短信支撐的其它電話* 身份驗證器運用
身份驗證器運用	開通短信支撐的電話 支撐語音功效的電話

如果您吸收驗證碼的重要裝備是：	您必需選擇以下任一選項作為您的備用裝備：
身份驗證器運用（手機）	支撐短信功效的電話（手機） 支撐語音功效的電話（固定電話或手機）
支撐短信功效的電話（手機）	支撐語音功效的不同電話（固定電話或手機）* 支撐短信功效的手機（手機）* 身份驗證器運用（手機）
支撐語音功效的電話（固定電話或手機）	支撐語音功效的不同電話（固定電話或手機）* 支撐短信功效的不同電話（手機） 身份驗證器運用（手機）

*對用于吸收驗證碼的重要裝備和備用裝備，電話號碼不能雷同。

通常情形下，您將只需通過重要辦法吸收驗證碼。然而，如果您無法應用重要辦法或未收到驗證碼，請點擊【沒有收到驗證碼？】以通過備用辦法吸收驗證碼。

如果用于吸收驗證碼的重要裝備的電話號碼喪失或涌現變動，您可以在應用備用裝備勝利登錄賣家平臺后更新此號碼。要更改您的主辦法和備用辦法，您必需能夠應用您的至少一個裝備。如果您既不能應用重要裝備，也不能應用備用裝備，請參閱兩步驗證賬戶恢復。

如果我沒有其它電話號碼或手機可用于兩步驗證，該怎么辦？

如果您沒有其他電話號碼或無法下載身份驗證器運用，我們建議您應用配偶、家人或朋友的電話號碼作為備用辦法。找到您信賴的人，并且在您無法應用重要辦法的情形下，能夠應用其電話號碼。

進行兩步驗證時不必定要應用移動電話。除了應用身份驗證器運用外，您還可以通過固話語音呼喚吸收驗證碼。

有關身份驗證器運用的更多信息，請參閱應用身份驗證器運用進行兩步驗證。

如何啟用兩步驗證？

如果您是未啟用兩步驗證的現有賣家平臺用戶，那么下次登錄賣家平臺時體系將提醒您激活兩步驗證。點擊【啟用兩步驗證】并依照屏幕上的解釋操作。

您也可以拜訪零售網站上的高等安全設置頁面，在該頁面上，您將履行雷同的操作。

• 兩步驗證與您用于拜訪亞馬遜賬戶的登錄憑證相干聯。如果您的亞馬遜買家賬戶和賣家賬戶應用的登錄憑證雷同，那么此驗證流程將同時對這兩個賬戶供給掩護。
• 如果您尚未履行這一操作，亞馬遜建議您通過用戶權限，應用不同的電子郵件地址為拜訪您賣家賬戶的每個用戶創立單獨的登錄憑證。如果不這樣做，您的賬戶以后可能會涌現安全風險，并可能會導致應用此特定登錄憑證的其他任何人都無法拜訪賣家賬戶。有關更多信息，請參閱設置用戶權限贊助主題。
• 如果您已經為拜訪您的賣家賬戶的每個用戶創立了單獨的賣家登錄信息，則須要分離對每個賬戶啟用兩步驗證。

有關啟用兩步驗證的分步指南，請參閱如何啟用兩步驗證。

登錄賬戶時，是否始終須要輸入我的兩步驗證碼？

通過兩步驗證流程勝利拜訪您的賬戶后，您可以簡化您的常用電腦和裝備以后的登錄進程。

下次在您的電腦或裝備上輸入驗證碼時，請告訴我們以后不請求在此裝備上輸入驗證碼，辦法是選擇【不請求在此裝備上輸入驗證碼】。

注意：此設置可能會因亞馬遜無法掌握的多種原因自行重置，因此我們無法贊助您解決您可能遇到的任何問題。但是，以下是可能干擾此功效的已知操作：

• 設置閱讀器以制止應用 Cookie
• 消除緩存或刪除 Cookie（檢討 Web 閱讀器設置）
• 更新電腦、裝備或裝備上的運用，包含 Web 閱讀器
• 從其他 Web 閱讀器拜訪賣家平臺，而不是之前添加過可信裝備的閱讀器
• 應用會影響閱讀器設置的閱讀器工具欄
• 應用匿名閱讀器模式或隱約身份信息的程序，包含應用代理和 VPN 服務器
• 如果已應用賣家移動運用，將其注銷可能會重置移動裝備上的可信裝備狀況
• 通過不同地位、網絡（LAN、WAN、WLAN）或更改后的 IP 地址拜訪賣家平臺。

多個用戶應用雷同的登錄憑證可能會增長這種情形的產生次數。確保拜訪您賬戶的每個用戶都有自己的登錄憑證。有關更多信息，請參閱設置和編纂用戶權限。

注意：您可以隨時拜訪“高等安全設置”，以肯定登錄時受信賴的裝備數目。在“高等安全設置”中，您可以通過選擇【請求在所有裝備上輸入驗證碼】來消除所有裝備的此設置。我們無法消除特定裝備的此設置；但是，消除所有裝備的此設置之后，您可以在下次登錄時選擇【不請求在此裝備上輸入驗證碼】選項。亞馬遜官網原文詳情：

What is Two-Step Verification?

Two-Step Verification is an extra layer of security that is added when you use your email address to access an account. When you log in to Seller Central, first enter your standard login/password. Then a second code that we send to a device that you choose via an SMS message, voice call, or an authenticator app.

Two-Step Verification is required in order to access your Seller Central account. It is your best protection against unauthorized access to your seller account, even if your password gets stolen and especially if you use the same password across multiple sites.

How does Two-Step Verification work?

When you access an account with a login that has Two-Step Verification enabled, you'll first enter your Seller Central user name and password like you normally would. Then, you'll be prompted to enter a code. This code is sent to the device that you choose during setup. Without access to that device, any unauthorized users attempting to log in to your account will be denied access.

What are the device requirements for Two-Step Verification?

When you first activate Two-Step Verification, you will need to designate two different devices for receiving codes. One will be your primary method for receiving codes and the other will serve as a backup if you lose access to the primary device.

You can receive codes using the following options: An authenticator app, voice call via mobile or landline phone, or via SMS. We recommend authenticator apps because they are easy to use, don’t require access to a network, and are readily available. They are free through app stores on personal computers, and smart devices – including mobile phones and tablets. For more information, SeeUse an authenticator app for Two-Step Verification.

You cannot use an authenticator app as both your primary and backup method. You must choose an SMS or voice enabled phone as either your primary or backup methods for receiving your code. The following table outlines both primary and backup options available to you:

If your primary method for receiving your code is:	You must select one of the following as your backup method:
SMS-enabled phone (for text messages)	Different voice-enabled phone* Different SMS-enabled phone* Authenticator app
Voice-enabled phone (landline)	Different voice-enabled phone* Different SMS-enabled phone* Authenticator app
Authenticator app	SMS-enabled phone Voice-enabled phone

If your primary method for receiving your code is:	You must select one of the following as your backup method:
Authenticator app (mobile)	SMS-text enabled phone (mobile) Voice-enabled phone (landline or mobile)
SMS text-enabled phone (mobile)	Different voice-enabled phone (landline or mobile)* Different SMS text-enabled phone (mobile)* Authenticator app (mobile)
Voice-enabled phone (landline or mobile)	Different voice-enabled phone (landline or mobile)* Different SMS text-enabled phone (mobile) Authenticator app (mobile)

* You cannot use the same telephone number for both your primary and backup method for receiving codes.

Typically, you will only use your primary method for receiving codes. However, if you don’t have access to your primary method or you are not receiving your code, clickDidn’t receive the code?to receive your code on your backup method.

If you lose or change the phone number of your primary method for receiving your code, update it in Seller Central once you have successfully logged in using your backup method. To make changes to your primary and secondary methods, you must have access to at least one of your devices. If you do not have access to either your primary or secondary methods – SeeTwo-Step Verification Account Recovery.

What if I don’t have a second phone number or a cell phone for Two-Step Verification?

If you do not have a second phone number or are unable to download an authenticator app, we recommend using the telephone number of a spouse, family member, or friend for your backup method. Find someone whom you trust and has a telephone number that you could be near if you lose access to your primary method.

A mobile phone is not a requirement for Two-Step Verification. In addition to using an authenticator app you can receive your code via a voice call to a landline.

For more information on authenticator apps, seeUse an authenticator app for Two-Step Verification.

How do I enable Two-Step Verification?

If you are an existing Seller Central user who has not enabled Two-Step Verification, you will be prompted to activate Two-Step Verification the next time you log in to Seller Central. ClickEnable Two-Step Verificationand follow the on-screen instructions.

You can also access theAdvanced Security Settingspage from the Retail site, which will take you through an identical experience.

• Two-Step Verification is tied to the login you use to access your Amazon accounts. If you use the same login for both your Amazon buyer and seller accounts, this process will protect both of them.
• If you haven’t already done so, Amazon recommends that you create inpidual logins with different email addresses, viaUser Permissions, for everyone accessing your seller account. Not doing so could pose a security risk for you in the future and could cause loss of access to anyone else using that particular login. See the Help topicSet user permissionsfor more information.
• If you already have inpidual seller logins for each user accessing your seller account, each account will need to enable Two-Step Verification separately.

For a step-by-step guide on enabling Two-Step Verification, seeHow to enable Two-Step Verification.

Do I always need to enter my Two-Step Verification code when I log in to my account?

After you have successfully accessed your account through the Two-Step Verification process, you can simplify future logins on computers and devices that you routinely use.

The next time you enter your code on your computer or device, tell us not to ask for a code on that device in the future by selectingDon't ask for codes on this device.

Note:This setting might reset itself for a number of reasons beyond Amazon’s control, so we’ll be unable to help you with any issues that you might experience. However, the following are known actions that may interfere with this feature:

• Setting your browser to block the use of cookies
• Clearing your cache or deleting cookies (check your web browser settings)
• Updates to your PC, device, or apps on your device, including your web browsers
• Accessing Seller Central from a web browser than the one you used to add your trusted device
• Using a browser toolbar that affects browser settings
• Using anonymous browser mode or programs that obscure identity, including the use of proxy and VPN servers
• If you’ve used the seller mobile app, logging out of it might reset the trusted device status on your mobile device
• Accessing Seller Central from different locations or networks (LAN, WAN, WLAN), or changes to your IP address

Having multiple users who use the same login credentials may increase these occurrences. Make sure that each person accessing your account has their own login credentials. SeeSet and edit user permissionsfor more information.

Note:You can access your Advanced Security Settings at any time to identify the number of devices that are “trusted” for your login. Here, you can clear this setting for ALL devices by selectingRequire codes on all devices. We don’t have the ability to clear the setting on specific devices; however, once all devices have been cleared, you can chooseDon’t ask for codes on this device option upon your next login.
