When safeguarding your online accounts, two-factor authentication (2FA) is an easy way to add another layer of protection. There are various solutions available to download, including the Google Authenticator app.
Technically, the Google Authenticator app produces time-based, one-time tokens that are tied to sites or accounts. A little timer tells you precisely how long you have left to enter the key before it expires, otherwise a fresh code will be generated. This prohibits the theft of one multiple-use key and is likely more than adequate for many folks out there wishing to add an extra layer of protection beyond simply their password for their online accounts.
The first setup method depends on a QR code or basic key, and while your Google account is now protected by your phone by default, for managing more than one service, Google Authenticator is still a wonderful free alternative, despite the laborious setup process.
As discovered by Android Police, the Google Authenticator app has officially reached the 100 million download mark on the Play Store. One small issue is that you need to transfer or export any accounts to a new device when you switch. However, should you lose your phone or it breaks, then sadly, you need to guarantee that you have synchronized across devices.
That said, it’s a basic program that offers nothing more than a dark background, yet it is capable of creating safe codes even without a cellphone or network connection. As such, updates have been few and far between, and the feature-set is relatively restricted.
