The Best Two-Factor Authentication App for Android  September 4, 2015 – 10:22 am

The Best Two-Factor Authentication App for AndroidTwo-factor authentication is one of the most important things you can do to protect yourself against getting your accounts hacked, and you should enable it now if you haven't already. Instead of using a text message, though, Authy is our favorite two-factor app on the block.

When you first enable two-factor authentication on a site like Gmail, LastPass, or Facebook, they will set you up using SMS as your second factor. So the next time you log into Facebook, you'll receive a 6-digit code as a text message whenever you try to log in. However, there are other ways to set up two-factor authentication—most notably, with an app that generates the codes for you.

You may have heard of these apps before, and a lot of the sites you use probably support them. They're handy because you don't have to rely on an incoming SMS message to log in—just open the app, and your codes are there waiting for you. In a lot of cases, they'll even work if you don't have an internet connection. Some of these apps do even more—like automatically log you in if your phone is near your computer. Our favorite, though, is Authy—here's why.

Platform: Android, iOS, Chrome, OS X
Price: Free


  • Install Authy on multiple devices including your phone, tablet, and PC, and sync your tokens between them
  • Backup your accounts to the cloud (optional, turned off by default)
  • Get tokens offline or when you don't have good service
  • Lock Authy behind a PIN so that even if your phone is stolen, your tokens aren't left out in the open

Where It Excels

When it comes to two-factor authentication apps, most are quite similar and support the same Google Authenticator-enabled services. Two main things set Authy apart: its ability to PIN lock the app (which alone makes it our favorite) and its ability to sync to the cloud and between devices. That means if you don't have your phone nearby, your tablet or PC work just as well. And, before you think installing Authy on a PC is insecure, keep in mind it's really no different than installing Authy on your phone—the goal is to keep your devices out of theives' hands, so that even if they get your passwords, they can't log into your account. It doesn't matter whether that device is a PC or a phone (and in fact, a phone is easier to steal).

Where It Falls Short

Some people may not want to sync their accounts to Authy's servers, since it puts it in the hands of someone else. Authy encrypts everything locally on your phone so they never see it, but some people may prefer not to sync their accounts to Authy's servers. This is hardly a con of the app, though, since this feature comes turned off, and it's completely optional. Even if you don't sync your tokens to the cloud, having the PIN lock and the ability to install Authy on your PC is totally worth picking it over other apps.

Some users have also had some quirkiness with Authy's syncing and its Bluetooth feature on the Mac, but I haven't experienced these myself.

The Competition

The most obvious competition to Authy is the app that started it all. Google Authenticator works great, it's free, it's from a company you know, and it's easy to set up. It is, however, the most basic of the options out there, so you won't get any extra features here—just basic two-factor tokens for tons of accounts.

FreeOTP is similar to Google Authenticator, though with a slightly nicer UI and an open source codebase. If you prefer open source when it comes to security, FreeOTP will do the trick.
