Overview

Amazon will require every Seller Central user to sign in with a passkey instead of a traditional password starting December 2 2025. The change forces sellers to register a device‑based biometric, facial scan, or PIN before that date, or risk being locked out of their accounts. Early adoption prevents interruptions to daily operations and aligns seller security with modern authentication standards.

Key Points

• Mandatory rollout date — The passkey requirement becomes enforceable on December 2 2025, giving sellers roughly nine months to transition.
• Biometric or PIN verification — Sellers will authenticate using a fingerprint, face ID, or device PIN, eliminating the need to remember or type passwords.
• Phishing resistance — Because authentication keys never travel over the internet, fake login pages cannot capture usable credentials, cutting the most common attack vector for seller account takeovers.
• Cross‑device synchronization — Passkeys stored in iCloud Keychain, Google Password Manager, or similar services automatically appear on a seller’s other Apple, Android, or Windows devices, removing the need for separate setup on each machine.
• Broad platform support — The feature works in Chrome, Safari, Edge, Firefox, and Amazon’s iOS/Android apps, ensuring consistent access regardless of the browser or device used.
• Team‑wide configuration – Every individual who logs into Seller Central—including virtual assistants, third‑party managers, and warehouse staff—must enroll a personal passkey on their own device, otherwise they will encounter sign‑in errors after the deadline.

How Passkey Verification Works

1. Initiate setup in Seller Central — A seller opens the “Login & Security” page, clicks the “Add Passkey” button, and the system prompts the device to generate a new cryptographic key pair. For example, a vendor using a 2023 iPhone sees a Face ID prompt that, once approved, creates a private key stored only on that phone.
2. Device registers the public key with Amazon — The newly created public key is sent to Amazon’s authentication server over an encrypted channel and linked to the seller’s account. A desktop user on Windows 11 experiences a pop‑up in Microsoft Edge asking to confirm the registration, after which the public key is saved on Amazon’s side.
