A one-time password generated for use with the Amazon platform is a dynamically created code that provides an additional layer of security during login or transaction verification. This code is typically delivered to a user’s registered mobile phone number or email address and is valid for a very limited time, usually just a few minutes. As an example, when logging into an Amazon account from a new device, the system may require the entry of a code sent via SMS to the registered phone.
The primary benefit of this security measure is to reduce the risk of unauthorized account access. Even if a password has been compromised, access is prevented without possession of the registered device. This substantially improves the overall security posture of the account. Historically, the implementation of one-time passwords has evolved as a response to increasing sophistication in cyber threats and the growing need for robust user authentication methods.
