There are a handful of good applications for this, but most sites use your text message phone number. Those that want to use authenticator applications have only a few good options. The best for Android is here!
Best two-factor authenticator apps for Android 2021
1. 2FA Authenticator
2FA Authenticator is an excellent choice for six digit TOTP authentication. It’s a simple app with a basic UI and it works pretty well. You can also add your secret key manually or via QR code if you want to. This one doesn’t have a whole ton of features, but it does the job it promises to do adequately and without issue. Of course, its simplicity prevents things like customization to a degree, but it works well nevertheless.
Authy is one of the two-factor authentication applications that are more secure. It functions like Google and the variants of Microsoft. You get code and use it to authenticate your relation. It works very well. The app also offers offline support, mobile syncing, and most common websites and account types are supported. If you want to use Google or Microsoft software, this is a perfect way to go. There are also no ads or in-app purchases completely free. For what it does, Authy’s good.
andOTP is one of the newer two-factor authenticator apps on the list. It’s completely free and open source. The app also supports the TOTP protocol. It’s not the most complicated app and that’s probably why people like it so far. It only needs a few permissions and the Play Store description tells you about all of them. Some other features of andOTP include multiple backup options, a dark mode, and compatibility with Google Authenticator. Those in the know can check out the open source code here.
4. Google Authenticator
Google Authenticator is arguably the most popular two-factor authenticator app. Google recommends it for all of your Google accounts. However, it also works for a variety of other websites. Some of the other features include Wear OS support, a dark theme, and offline support. This is the one I personally use all the time. There’s no specific reason for it because all the apps on this list work just as well. It just happened to be the first one I set up. In any case, it’s completely free, it’s clean, it works, and it’s widely supported. The only pain point is the set up process and it’s not even all that bad.
5. Microsoft Authenticator
Google’s greatest competitor is Microsoft Authenticator. It works well, and for things other than Microsoft apps. It’s famous. If not, it’s really quite a simple app that doesn’t vary from Google Authenticator. You log in, request a code, and open the app to get it. You can also access an app. For people who use Google services heavily, we typically suggest Google Authenticator. Microsoft has the same thing. Those using Microsoft would probably be more comfortable with this than the other applications in the list. There are also no advertisements or in-app purchases available free of charge.
