Passwords are no longer secure, you may think you have some out of the box version of a password, but that doesn’t mean that you are safe, and that’s where two-factor authentication comes in, it allows users to add an extra security layer to their account by requiring a second password from a verified device.
As of yet the adoption rate for this technology has been extremely low, with only a few services like Facebook, Twitter, Google, Dropbox and Apple offering the security feature, however after trailing the feature in a beta testing phase, Amazon has finally joined that list, enabling two-factor authentication for Amazon.com and allowing all of its customers to secure their account either via text message authentication, or via an authentication app of their choice.
Amazon explains a little more :
You’ll enter your sign in information like you normally would, but then you’ll be prompted to enter a security code. You can receive this security code in a variety of ways depending on the option you select during sign up, including text message, voice call, or authenticator app.
To simplify sign-in on computers and devices that you routinely use, you can tell us not to ask for a security code so that you won’t need to enter a code each time you sign in. Afterward, that computer or device will only ask for your password when you sign in.
If you need help from Customer Service after enabling Two-Step Verification, you’ll need provide a security code similar to when trying to sign in to your account.
