OTP

 A One-Time Password (OTP) is a security feature used by Amazon and many other digital platforms to protect accounts and sensitive actions. It’s typically a numerical code, sent via email, SMS, or authenticator app, and is valid for only a short duration or a single session.

Where Amazon uses OTPs:

• Two-Step Verification (2SV) for Seller Central or AWS logins
• Customer delivery verification (for high-value shipments in some regions)
• Password resets or account recovery
• Sensitive changes (e.g., payment methods, contact info, permissions)

Why OTP matters:

• Strengthens account security by preventing unauthorized access
• Helps authenticate the user’s identity before allowing access or changes
• Required for compliance with security policies, especially for sellers handling large volumes or accessing financial data

💡 Example: A seller logging into Seller Central from a new device receives an OTP via text to verify it’s really them.

In short:
OTP (One-Time Password) is a temporary security code used by Amazon to verify user identity during logins or sensitive actions - an essential tool for protecting accounts and transactions.
