How to Set Up an Authenticator App for Amazon Seller Central Two-Step Verification
Amazon Seller Central requires Two-Step Verification, and using an authenticator app is the most reliable method. This guide covers supported apps, setup steps, and best practices for securing seller accounts.
Overview
Amazon requires Two-Step Verification (2SV) for all Seller Central accounts, and using an authenticator app is one of the most reliable ways to meet this requirement. Rather than waiting for a text message or voice call each time you sign in, an authenticator app generates time-based codes directly on your device — no phone service or internet connection needed. For sellers managing high-value accounts, understanding how to properly configure this security layer is essential.
Key Points / What Sellers Need to Know
- Authenticator apps work offline — Unlike SMS-based verification, authenticator apps generate codes locally on your device without requiring cellular service or an active internet connection, making them more reliable for sellers on the go.
- Multiple platforms supported — Authenticator apps are available for iOS, Android, and Windows devices, giving sellers flexibility in how they secure their accounts.
- TOTP standard required — Any authenticator app you choose must support the TOTP (Time-based One-Time Password) standard, which is the open protocol Amazon uses for code generation.
- USB security keys are also an option — For sellers who prefer hardware-based authentication, Amazon supports USB security keys as an alternative or additional verification method.
- Apps cannot access your credentials — Authenticator apps do not have access to your Amazon password or account information, so using one does not introduce additional security risk.
How It Works
When you enable an authenticator app for Two-Step Verification, the app generates a new six-digit code every 30 seconds using the TOTP protocol. During sign-in, instead of waiting for a text message, you simply open the app and enter the current code. This approach eliminates common issues with SMS delivery delays, international phone number complications, and SIM-swapping attacks that can compromise text-based verification. Amazon provides two methods to link your seller account to your chosen authenticator app: scanning a QR code displayed on screen, or manually entering a secret key into the app.
