Best privacy and security apps for Linux

Best privacy and security apps for linux

Here are some of the best of the best security and privacy apps for Linux. Using Linux means that you value security and privacy. Here are some of the best FOSS (Free and Open-Source Software) that I have come across. Download them and check out some great programs to keep you safer on the internet.

1. Tor Browser

The Tor Project

Development of Tor Browser began in 2008. The Electronic Frontier Foundation (EFF) helps to fund the project.

Tor Browser download page. Here are the directions to install and set it up.


2. Bitwarden

Bitwarden Password Manager

Bitwarden is one of the best open-source projects, and the password manager that I use on my computers and other devices.

If you’re on Ubuntu, Debian, Linux Mint, and the like, download the DEB package for Bitwarden first.

On Fedora, CentOS, RHEL, or openSUSE, grab the RPM package for Bitwarden.

To install Bitwarden on Arch Linux and its derivatives, run:

sudo pacman -S bitwarden



3. Authenticator

Authenticator (Gnome)

Authenticator 2FA desktop client on Linux is used for over 200 sites for 2FA credentials.

To install it, you will need Flatpak:

sudo apt-get install flatpak -y

Add the Flathub repository with:

flatpak remote-add –if-not-exists flathub

Restart your machine to continue.

Now that Flatpak is installed, you can install Authenticator with this command:

flatpak install flathub com.belmoussaoui.Authenticator



4. VeraCrypt


You can create encrypted file volumes within container files. VeraCrypt file volumes can only be decrypted and mounted through the app.  So, for example, you can create an 8 Gb encrypted file volume hidden under a container file named “Star_Wars_Complete.mkv”. If it is your Videos file, it is hidden right there in plain sight.  It looks like the rest of your .mkv files. It is password protected (remember to make it a good, long, complex password).

You can download a copy of the program here.

5. Kleopatra


GnuPG (which allows users to create OpenPGP keys) is normally used through a command line, but with Kleopatra, you’ll be able to use GnuPG through a GUI.  Kleopatra is a tool to encrypt and authenticate text and files using the OpenPGP standard.

You can download Kleopatra by clicking here.

6.  Chkrootkit


chkrootkit is a tool to locally check for signs of a rootkit. It contains: chkrootkit: shell script that checks system binaries for rootkit modification.

Install it at the command line by typing:

sudo apt install chkrootkit -y

Then run the command:

sudo chkrootkit

7.  Gufw


UFW (Uncomplicated Firewall) is a simple-to-use firewall utility with plenty of options for most users. It is an interface for the iptables (a low-level tool to set up rules for your network).

Gufw is a GUI version of the command line tool and is simple to use.

To get it, on Ubuntu (or derivatives) open a command prompt and type in:
