Amazon Seller Central Login 2027: Sign-In, Passkeys and Fixes

Amazon Seller Central login looks simple until it stops working: a verification code that never arrives, a passkey prompt that loops, or a sign-in page that sends you to the wrong marketplace. This 2027 guide covers how to sign in, how two-step verification and passkeys work now, how to fix the most common lockouts, and how to keep your account safe from phishing and shared-login risk.

How to log in to Amazon Seller Central

Seller Central is the dashboard where you manage listings, inventory, orders, advertising and payments. For the US marketplace, the sign-in page lives on sellercentral.amazon.com. Other regions use their own Seller Central domains, and your account is tied to the marketplace you registered in, so always start from the address Amazon gave you at registration.

Step by step

1. Open the Seller Central address for your home marketplace in a current browser.
2. Enter the email and password you used when you registered the seller account.
3. Complete the verification prompt (a one-time code, an authenticator app code, or a passkey).
4. Choose the marketplace you want to work in from the marketplace switcher at the top of the dashboard.

If you have not finished registration, the sign-in page will route you back into the sign-up flow. Registration involves choosing a plan, adding business, payment and tax details, and completing identity verification before the account activates.

Seller Central vs. a regular Amazon account

A buyer account and a seller account share the same login technology, but they are separate things in practice. Many sellers register with the same email as their shopping account, which creates confusion when you reset a password or change a phone number. Keep a dedicated business email for the seller account and document who has access to it.

Two-step verification and passkeys in 2027

Amazon has been tightening Seller Central sign-in for several years. In 2024 it announced that, starting as early as March 28, 2024, sellers would be required to verify their identity at sign-in using a mobile number or an authenticator app. The two methods work like this:

• Mobile number: Amazon texts you a one-time code.
• Authenticator app: an app on your device generates a time-based code. You register it under Login Settings.

Amazon recommends an authenticator app for accounts with several users and for moments when cell service is unreliable.

Passkeys

In December 2025, Amazon announced that passkey verification was coming to Seller Central sign-in and that it was encouraging passkey use for all accounts. A passkey replaces typing a code with your device's fingerprint, face scan or PIN. Amazon's guidance at the time said:

• Set it up from Login Settings by selecting Set Up next to Passkey.
• You can still use your password if you prefer.
• You can create only one passkey per passkey provider.
• Supported devices need recent operating systems (iOS 16, macOS Big Sur, Android 9 or Windows 11 at the time of the announcement) and an up-to-date browser.

Seller forum threads from that period showed mixed experiences, including setup buttons that did not respond and sellers who were still asked for an authenticator code after using a passkey. Rules change, so check the Login Settings page in your own account for what is currently available and required.

A sensible setup

• Register an authenticator app as your primary method, and keep the phone number as a backup.
• Add a passkey on a device you control.
• Save the backup codes offline in a password manager or a locked document.
• Do not share one phone number across several people who need access. Give each person their own user permissions instead.

Fixing common Seller Central login problems

Forgot password

Use the password reset option on the sign-in page. Amazon sends a reset link to the registered email and may ask you to confirm details on file. If you no longer have access to that email, you need to recover the mailbox first, then proceed.

Verification code never arrives

• Check that the phone number on the account is current.
• Wait a minute and request a new code once rather than repeatedly.
• Switch to the authenticator app or a saved backup code.
• If none of those work, reset two-step verification from the security settings after verifying your identity.

Authenticator app out of sync

Time-based codes depend on your phone clock. Turn on automatic date and time, then try again. If you switched phones, you need to re-register the app, which is easiest when you still have an old device or backup codes.

Wrong marketplace or redirect loop

Make sure you are using the Seller Central address that matches the marketplace you registered. Clear cookies for the Amazon domains or use a private window if the page keeps redirecting.

Account locked or suspended

If the account is deactivated or under review, logging in may show a notice instead of the dashboard. Respond through the Account Health and Seller Support paths in Help, and provide the documents Amazon requests. Do not open a second seller account to work around it, because duplicate accounts can create further trouble.

Repeated identity verification requests

Resubmit documents that match the name, address and tax details on file exactly. If requests keep coming, open a support case rather than resubmitting indefinitely.

Staying secure: phishing and shared access

Seller accounts are valuable targets because they sit on top of payments, inventory and customer data.

• Check the URL before you type credentials. Bookmark your Seller Central address and use the bookmark.
• Treat urgent emails with suspicion, especially those threatening suspension unless you click a link. Go to Seller Central directly and check Performance notifications instead.
• Use secondary users, not shared passwords. Invite teammates, agencies and VAs with the minimum permissions they need, and remove them when the engagement ends.
• Review who has access every quarter, including old freelancers and tool integrations.
• Be careful with third-party tools. Authorize only reputable apps, and review the list of connected apps periodically. Our guide to the best Amazon seller tools is a good starting point for vetting software, and the Cruxfinder directory lists vendors in the space.

The GTM angle

Login and access friction is a quiet but constant pain point for Amazon sellers, and that makes it useful for anyone selling to them. Agencies need access to client accounts. Tool vendors need sellers to authorize integrations. Both get stuck on the same issues covered above.

Here is how to turn that into pipeline:

• Trigger-based cold email. Target sellers who recently hired an agency, switched tools or added team members, and open with a concrete line on how you handle access safely using secondary-user permissions.
• ICP segmentation. Multi-user brands with several marketplaces feel access complexity most. Segment by team size and number of storefronts, and tailor the offer: an onboarding checklist for agencies, a permissions template for software vendors.
• Offers that reduce friction. A one-page "how to give us access safely" guide removes a real objection and builds trust before the first call.
• Content-led outreach. Sellers searching for login help are active users. Publish helpful guides, then retarget readers with relevant ads.
