In this tutorial, we will walk through the steps of installing 2FAuth, a two-factor authentication script from https://github.com/Bubka/2FAuth, on Elementary OS Latest.
Before we begin, ensure you have the following:
The first step is to install Git. This is required to download the 2FAuth script from GitHub.
To do this, open a terminal and run the following command:
sudo apt install git
After the installation is complete, verify the installation by running the command:
git --version
If Git is installed successfully, you will see its version number.
Now that Git is installed, we can download 2FAuth from GitHub.
To do this, navigate to the directory where you want to install 2FAuth using the cd command.
cd /path/to/directory
Then, clone the 2FAuth repository from GitHub using the following command:
git clone https://github.com/Bubka/2FAuth.git
This command will download the 2FAuth script from GitHub and save it in your current directory.
The next step is to install the dependencies required to run 2FAuth.
To do this, navigate to the 2FAuth directory and run the following command:
cd 2FAuth
sudo apt-get install qrencode oathtool
This command will install the qrencode and oathtool packages.
Now that we have downloaded the script and installed the required dependencies, we can install 2FAuth.
To do this, run the following command:
sudo ./install.sh
This command will run the installation script which will copy the required files to your system and create a new user called 2FAuth.
2FAuth is now installed and ready to use.
To create a new user, run the following command:
sudo su - 2FAuth
./newuser.sh
This command will prompt you for a username and a shared secret. Once you provide these details, 2FAuth will generate a QR code that you can scan with a two-factor authentication app such as Google Authenticator.
To generate an OTP for a user, run the following command:
sudo su - 2FAuth
./gen.sh <username>
This command will generate an OTP that can be used for two-factor authentication.
2FAuth has been successfully installed on your Elementary OS Latest machine. You can now use it to secure your SSH connections and other services that require two-factor authentication.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
