Currently you can further secure your account by getting a code via text message (or phone call), or with a code from the Authenticator app. A new prompt adds a third option. enever you go to sign in somewhere new with your account, you’ll see a simple pop-up notice to approve or deny the request. The feature will soon be native to Android devices through an update to ay Services. On iOS, the approval prompt will come through the app. To flip this on for your account, head to the My Account page. Then, go to Sign-in & Security > Signing in to > 2-Step Verification. You’ll then be able to choose from among any active phones. You’ll get a test prompt to verify that everything works, then the prompt will be your default method.  The impact on you: Two-factor authentication is essentially a must-have feature to protect all that important data saved to your account. th this update, the sign-in process is much easier. It’s more secure than an SMS code (which has been subject to exploits) is faster than launching the Authenticator app typing in a code.
