+Authenticator: A Simple Open-Source App to Replace Authy on Linux
+======
+
+Authy is a popular app for storing and managing two-factor codes. It is a cloud-based service that gives you convenience with industry-grade security. Unfortunately, it is not open-source.
+
+Would you consider using a more straightforward (and open-source) authenticator app on your Linux desktop?
+
+Well, of course, you cannot cloud sync here. But you can generate a backup for the two-factor authentication codes. Keeping that in mind, let me tell you more about Authenticator.

+
+### Authenticator: Generate Two-Factor Authentication Codes
+
+When you enable two-factor authentication with online services, most services give you a token/QR code that you can add/scan to generate codes.
+
+Authenticator is one such app for Linux that lets you add two-factor authentication codes.
+
+![authenticator ui][2]
+
+It is a free and open-source app with essential features to add a variety of tokens and websites that support two-factor authentication.

+
+### Features of Authenticator
+

+
+Some of the essential options that you get with it include:
+
+- QR Code scanner using a camera or a screenshot
+- Protect the app using a passphrase
+- Autolock the app
+- Support for different algorithms (SHA-1/SHA-256/SHA-512)
+- Time-based/Counter-based/Steam computing methods supported
+- Backup/Restore options (FreeOTP, Aegis, andOTP, Bitwarden, and Google Authenticator)
+
+You get customization options and the ability to add a custom provider as per the support provided by the service. One can add a custom icon for the provider to help you distinguish between the authentication codes.

+
+For the most part, the default settings should work with websites. However, you might want to check the exact details with the provider if it does not work. 
+
+The app also features multiple providers out of the box, like Google Drive and Proton Mail. So, you do not need to add custom configurations for every entry you add.
+
+### Installing Authenticator on Linux
+
+![authenticator add new code][6]
+
+Authenticator is available as a Flatpak. So, you can install it on any Linux distribution.
+
+Just type in the following command to get it installed:
+
+```
+flatpak install flathub com.belmoussaoui.Authenticator
+```
+
+You can head to its [Flathub][7] or GitLab page to explore more.
+
+If you are new to the Linux world, refer to our [Flatpak guide][8] to set it up. Your software center might already have Flatpak integration enabled out of the box. You can search for it to get it installed in such a case.
+
+### Use Open Source Authenticator App For Security and Reliability
+
+We often depend on cloud-powered tools for everything. Sure, it is convenient.
+
+However, sometimes desktop apps are more helpful. If you are in the same boat and thinking of making a switch, Authenticator can be an excellent app to have installed for two-factor authentication codes.
