Two-factor authentication, often known as 2FA, refers to an extra login code required to access your account. Accounts being hacked has become the norm these days, therefore you must exercise extreme caution by utilising strong passwords and two-factor authentication.
Even if the hacker steals your password and username, gaining access to your account will be difficult since it will prompt you for an authentication code that will appear on your smartphone if you use Two-Factor Authenticator applications. When you utilise 2FA, each service you log in to will require two authentications: the password you know and the authentication code from the app.
When compared to websites, using two-factor authenticator applications on cellphones provides less alternatives. Here are a few Two-Factor Authenticator Apps for Android.
List of the Top Android Two-Factor Authenticator Apps
The Authy two-factor authenticator app functions similarly to Google and Microsoft’s versions. The codes are used to authenticate your login and are supplied by the app. The app also allows offline device synchronisation and a large number of sites and accounts. One of the nicest features is that it is completely free, with no adverts or in-app purchases.
2. Google Authenticator
It is one of Google’s most popular two-factor authenticator applications. The Google Authenticator app is recommended for all Google accounts. It works for many more websites in addition to Google accounts.
It runs offline, supports Wear OS, and has a dark theme. An app’s User Interface is highly clean and simple to use, and it is supported by a wide range of devices. However, you will have some difficulty setting it up.
3. Microsoft Authenticator
The Microsoft Authenticator app performs admirably, even when used with apps other than Microsoft’s. When you log in to any app or website, it will ask for a code, which this app will provide. If you use Google Services frequently, Google Authenticator is a better option.
The same holds true for Microsoft users. If you use Microsoft frequently, this app is for you because it is free, there are no in-app purchases, and there are no advertising.
4. TOTP Authenticator
TOTP Authenticator is a simple and powerful app that is compatible with a wide range of devices. This app, on the other hand, has a dark theme setting, a fingerprint scanner, Widgets, and cross-platform integration via Extention with iOS and Google Chrome. When you make changes, you can see them on all of your devices thanks to cloud synchronisation. This app is free, but there are in-app purchases available.
5. 2FA Authenticator
2FA Authenticator is a straightforward and free 2FA app. It creates Time-based One-time Passwords (TOTP) and performs Push authentication. This app only supports the six-digit TOTP factor. It works nicely with the simple UI, and you can manually enter your secret key or utilise the QR code. This app does not have many features, but it functions flawlessly.
AndOTP is a two-factor authenticator app that is both free and open source. Simply scan the QR code and enter the 6-digit number to log in. The TOTP protocol is supported by this app. The majority of them choose this app because it is simple to use.
It requires only the most basic permissions, such as camera access for QR code scanning and storage access for database import and export. It features several theme options, including Light, Dark, and Black (for OLED screens).
7. Aegis Authenticator
Aegis Authenticator is one of the most popular 2FA applications. HOTP and TOTP are the two algorithms supported by Aegis. These algorithms are extensively supported, making this app compatible with a wide range of services.
Aegis Authenticator will operate with any online service that supports Google Authenticator. It contains fantastic features, such as the ability to lock and access the app using a PIN, password, or fingerprint. You may also backup your account and export it to a new device.
8. FreeOTP Authenticator
It is a free and open-source authenticator app that works with many of the internet services you are already familiar with, such as Google, Facebook, GitHub, and others. If they follow the conventional TOTP or HOTP protocols, FreeOTP can also function with private corporate security.
It is a low-cost alternative for small enterprises. However, while this is not the most popular option for authenticator applications, it performs admirably.
