Overview

Two-Step Verification (2SV) is a mandatory security feature for all Amazon Seller Central accounts. It adds a second layer of authentication beyond your standard password, requiring you to confirm your identity through an additional device each time you sign in. For Amazon sellers, enabling and maintaining 2SV is not optional — it is a baseline requirement for accessing your account and safeguarding your business from unauthorized access.

Key Points / What Sellers Need to Know

• 2SV is mandatory for all seller accounts — Amazon requires Two-Step Verification as a condition of accessing Seller Central. You cannot opt out of this security measure.
• It works alongside your existing password — After entering your email and password, you must provide a second verification code before gaining access to your account.
• Multiple verification methods are available — Sellers can receive their second-factor code via SMS text message, voice call, or through an authenticator app installed on a mobile device.
• Authenticator apps are the most reliable option — Apps like Google Authenticator, Microsoft Authenticator, or Authy generate time-based codes that work even without cell service, making them more dependable than SMS.
• It protects against password theft — Even if your password is compromised through a phishing attack or data breach, an attacker cannot access your account without also having your second verification device.

How Two-Step Verification Works

When you navigate to Seller Central and enter your login credentials, Amazon immediately prompts you for a second form of authentication. Depending on your chosen method, you will either receive a one-time code via text message or voice call to your registered phone number, or you will open your authenticator app to retrieve a time-sensitive code. You then enter this code on the login screen to complete the sign-in process. The code changes regularly and expires quickly, so even if someone intercepts a single code, it cannot be reused. This two-layer approach ensures that access to your seller account requires both something you know (your password) and something you have (your verification device).
