Account Security

What It Is

Your Account Is Only as Secure as its Login

With hackers developing more sophisticated attacks to harvest users’ login credentials, taking a strong approach to security will benefit both merchants and consumers. The Shift4 Authenticator application, is a multifactor authentication tool that helps secure your accounts and keep the sensitive information within them safe.

Whenever you log in to your Shift4 Lighthouse Transaction Manager and MyPortal accounts (plus any other accounts that support Google Authenticator), Shift4 Authenticator generates a unique six-digit passcode on your iOS device that you can enter along with your username and password. Passcodes change every 30 seconds, so your account access is linked directly to your physical device, providing an additional layer of security and better protecting your accounts from hackers. Now, not only would they have to steal your username and password, they’d also have to physically access your phone to open the Shift4 Authenticator app.
