By using any type of USB storage device and PAM, we can create the authentication token:
- To start with, we first need to install the packages required for PAM USB authentication. To do so, we run this command:
$ sudo apt-get install pamusb-tools libpam-usb
- Once the packages are installed, we have to configure the USB device to use PAM authentication. To do so, we can either use a command, or else we can edit the /etc/pamusb.conf file.
To use the command method, first connect the USB device, and after that execute this command:
$ sudopamusb-conf --add-device usb-device
In the preceding command, usb-device is the name ...
