About Two-Step Verification

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 sign-in to Seller Central, you will enter your standard sign-in/password and 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 and is your best protection against unauthorized access to your seller account, even if your password is 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 sign-in 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 you chose during setup. Without access to that device, any unauthorized users attempting to sign-in to your account will be denied access.

You cannot use an authenticator app as both your primary and backup method, so you have to 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:
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, you can have your code sent to your backup method by clicking Didn’t receive the code?

If you lose or change the phone number of your primary method for receiving your code, you can always 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 – See Two-Step Verification Account Recovery.

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

What if I don’t have a second phone number or a mobile 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 – someone 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 always receive your code via a voice call to a landline.

For more information on authenticator apps, see Use 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 sign-in to Seller Central. Click “Enable Two-Step Verification” and follow the on-screen instructions.

You can also access the Advanced Security Settings page from the Retail site, which will take you through an identical experience.

  • Two-Step Verification is tied to the sign-in you use to access your Amazon accounts. If you use the same sign-in 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 individual logins with different email addresses, via User 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 sign-in. See the Help topic Set user permissions for more information.
  • If you already have individual seller logins for each user accessing your seller account, each account will need to enable Two-Step Verification separately.

Do I always need to enter my Two-Step Verification code when I log into 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 clicking the check box next to Don't ask for codes on this 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 sign-in credentials may increase these occurrences, so make sure that each person accessing your account has their own sign-in credentials.

Here, you can clear this setting for ALL devices by selecting Require 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 choose Don’t ask for codes on this device option upon your next sign-in.
