Users can go into their account settings to enable two-step authentication, which prompts the need for a code taken from another service, such as through an authenticator app or an SMS message to a mobile device. Two-step authentication is popular for adding an extra layer of safety to help protect user information from hackers.

Amazon made no official announcement about offering the service, according to The Verge. Fortune has reached out to the company for comment.

The way it works is pretty simple: Log in to your Amazon account, get to “account settings,” and then open up “advanced account settings.” Once there, there’s now the option to enable two-step authentication through an authenticator app, such as Google Authenticator, or through a mobile device with a text message.

Per Amazon’s site: “No one can access your account if your password alone is compromised.”

In July, Snapchat began offering two-step authentication to bolster app security.
