Your online accounts are much safer when you rely on more than only a password, and that's where two-factor authentication (2FA) apps come in. You can use them to create an extra layer of security for your accounts, requiring you to enter a one-time password (OTP) in addition to your regular credentials when you log in. That prevents hackers from accessing your account with a stolen password only.
The Google Authenticator app has undergone its first facelift since 2017, making the jump from version 5.0 to 5.10. But the visual makeover — including a much-needed adaptation to newer phones' aspect ratios — belies a major change that will make it easy for you to port your keys over to another phone.
Using app-generated one-time passcodes (OTPs) is perhaps the easiest and most cost-effective way to add a second authentication layer to all your online accounts and services. They eliminate almost any chances of an unauthorized person accessing your accounts even if they’ve got hold of your passwords. But it would be a scary situation if the passcodes within those apps were compromised, and that's just the threat Google Authenticator is facing right now thanks to some banking malware.
Google Authenticator is one of many two-factor authentication apps available for Android. While Google's attention is more focused on phone login prompts, Authenticator remains a popular choice for having all your 2FA codes for all your accounts in one place. The app has now been updated to v5.0, with a few useful additions in store.
Setting up and using 2-factor authentication on a Google account used to be a fairly miserable affair. The sign-in process lurched from a native interface into a browser where users were expected to quickly enter codes, various apps weren't compatible and required special 1-time use passwords, and the app for generating codes felt completely unfinished. These days, all of those problems have been solved, and now Google's Authenticator app is even taking steps to further improve its look and usefulness. The latest update brings a great looking refresh to the UI, adds a dark mode, and finally adds its own built-in scanner functionality.
Many of Google's apps are in extremely active development, some are even on weekly update schedules, but there are others that seem practically abandoned until they get that one random update every 6 months or so. With an average of about once per year (so far), Authenticator is easily one of the best examples of the latter group. Given the infrequency of new versions, it's a little disheartening to see that there are no discernable new features in the latest release; but it's actually worse than that, one was even taken away. But don't let this get you down, it looks like this little app may be due for some new tricks soon as it may be entering wireless territory.
Account security is a tough issue for a lot of people. It's a constant balancing act between having a stronger system to keep out would-be invaders while also making it convenient enough that users won't reject it. After Google began offering its own 2-step verification system, several other services adopted the same mechanism and opt-in model for people that wanted more than a single password protecting their personal data. This generally left users with Google's Authenticator app, which got the job done, but it lacked features and languished on an early Holo dark design. If you're looking for something a little more modern and functional, it's time to check out Authy.
