Google Authenticator is a popular iOS and Android app that adds another layer of two-factor authentication for websites and apps. Once you have installed Google Authenticator on your device, you can add various websites and apps to it by scanning a unique QR code. Now, whenever you log in to these platforms, a unique one-time generated code would be displayed on Google Authenticator that you need to match on their log-in page. This is a perfect alternative to an SMS-based two-factor authentication process and is ideally more reliable.
