If you’re serious about securing your online accounts, then you should already be using unique, strong passwords for your online properties, preferably with the help of a password manager. On top of that, many products and services now support two-factor authentication (2FA), which adds another layer of protection on top of that password. You should be using 2FA with all your valuable accounts, especially the ones you use to manage money and personal data. It’s one thing for hackers to steal your Netflix account, and quite another for thieves to get control of a banking app or email account. But even 2FA is not always convenient, especially if it involves entering a code you’ve just received via SMS. A better alternative is actually using a standalone gadget to act as your 2FA authenticator. And, the iPhone happens to be one such device, when it comes to Google accounts. Your Google account holds the keys to a treasure trove of data, as it controls all your Google properties, including Gmail, Search, YouTube, Maps, and many others.
