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.
|
|
|
|

|
|
|
|
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.
