How to Install and Use KeePassXC on Linux: A Comprehensive Guide

In today’s digital age, managing passwords securely is more important than ever. KeePassXC, an open-source password manager, offers robust security features that help you manage your passwords efficiently. This article will guide you through the process of installing and using KeePassXC on a Linux system.

Introduction to KeePassXC

KeePassXC is a community-developed fork of KeePassX, which itself is a cross-platform port of the KeePass password manager. KeePassXC supports a wide range of features, including multi-platform support, browser integration, TOTP (Time-based One-Time Password) generation, and a secure password generator. Its open-source nature ensures transparency, and its active community continuously updates it with new features and security enhancements.

Step 1: Installing KeePassXC on Linux

KeePassXC is available on most Linux distributions through their package managers. Depending on your distribution, you can install KeePassXC using different methods.

Installing KeePassXC on Ubuntu/Debian

On Ubuntu or Debian-based distributions, installing KeePassXC is straightforward using the APT package manager.

Update your package list: Open a terminal and type the following command to ensure your package list is up to date:

sudo apt update

Install KeePassXC: Once the package list is updated, install KeePassXC by typing:

sudo apt install keepassxc

Verify the installation: After the installation is complete, you can verify it by running:

keepassxc --version

This command should display the version number of KeePassXC installed on your system.

Step 2: Setting Up KeePassXC for the First Time

After installing KeePassXC, you need to set it up to start managing your passwords. This involves creating a new database and configuring some basic settings.

Creating a New Database

1. Open KeePassXC: Launch KeePassXC from your applications menu or by typing keepassxc in the terminal.
2. Create a new database: Click on the “New Database” button in the main window. This will start the database creation wizard.
3. Set a master password: Choose a strong master password for your database. This password will protect all the passwords stored in the database, so it must be secure and memorable.
4. Configure database settings: In the next step, you can configure advanced settings such as encryption algorithms and key derivation function (KDF). The default settings are usually sufficient for most users.
5. Save the database: After configuring the settings, save your database to a secure location. Choose a file name and location that you will remember, but avoid saving it in easily accessible locations.

Configuring Basic Settings

1. General settings: After creating your database, navigate to the “Settings” menu. Here you can configure general preferences such as auto-lock behavior, user interface themes, and language.
2. Security settings: In the security tab, you can adjust settings like clipboard protection, auto-type security, and password generator options. Enabling clipboard clearing after a few seconds is a good practice for added security.
3. Backup settings: KeePassXC can automatically create backups of your database. Configure backup settings under the “Database” menu to ensure you don’t lose your passwords.

Step 3: Adding and Managing Entries

Once your database is set up, you can start adding your passwords and managing them efficiently.

Adding a New Entry

1. Create a new entry: To add a new password, click the “Add New Entry” button in the toolbar. This will open a new entry form.
2. Fill in the details: Enter the title, username, password, and URL associated with the account. You can also add notes and tags to categorize your entries better.
3. Use the password generator: KeePassXC includes a built-in password generator. Click on the “Dice” icon next to the password field to generate a strong, random password.
4. Save the entry: Once you’ve filled in all the necessary details, click “OK” to save the entry.

Organizing Entries

1. Create groups: KeePassXC allows you to organize your entries into groups. To create a new group, right-click on the database tree and select “Add New Group.” Name the group according to the category, such as “Work,” “Personal,” or “Social Media.”
2. Move entries to groups: Drag and drop your entries into the appropriate groups. This keeps your database organized and makes it easier to find specific entries.
3. Search functionality: KeePassXC offers a powerful search feature. Use the search bar at the top to quickly find entries by name, username, or URL.

Step 4: Using Browser Integration

KeePassXC can be integrated with web browsers to automatically fill in your login details. This feature is supported by popular browsers like Firefox and Chrome through the KeePassXC-Browser extension.

Installing KeePassXC-Browser

1. Install the extension: Visit the extension store for your browser (Firefox Add-ons or Chrome Web Store) and search for “KeePassXC-Browser.” Install the extension.
2. Enable browser integration in KeePassXC: Open KeePassXC, go to “Settings,” and then select “Browser Integration.” Enable the browser integration and choose the browsers you want to integrate with.
3. Connect KeePassXC to the browser: After enabling the integration, click the KeePassXC icon in your browser toolbar. This will prompt you to connect to the KeePassXC application. Approve the connection request.

Using the Browser Extension

1. Auto-fill login forms: When you visit a website where you have saved credentials, click the KeePassXC icon in the browser toolbar. Select the appropriate entry from the list, and the extension will automatically fill in your username and password.
2. Saving new credentials: When you create a new account or change a password on a website, KeePassXC-Browser will prompt you to save the new credentials. Click “Save” to add them to your KeePassXC database.
3. Manage your credentials: You can manage your saved credentials directly from the browser extension. Click on the KeePassXC icon, select “Manage Entries,” and make changes as needed.

Step 5: Backing Up and Syncing Your Database

To ensure your passwords are always safe and accessible, it’s essential to back up your KeePassXC database regularly. Additionally, you can sync your database across multiple devices.

Creating Backups

1. Manual backup: Regularly copy your KeePassXC database file to a secure external drive or cloud storage. This manual process ensures you have a backup in case of data loss.
2. Automated backups: KeePassXC can create automated backups. Go to “Database Settings,” then select “Backup.” Configure the settings to automatically save backup copies after each modification.

Syncing Your Database Across Devices

1. Use a cloud storage service: Store your KeePassXC database in a cloud storage service like Dropbox, Google Drive, or Nextcloud. This allows you to access the same database from multiple devices.
2. Install KeePassXC on other devices: Ensure KeePassXC is installed on all devices you wish to use. Sync the database by opening the cloud-stored file on each device.
3. Keep the database updated: When making changes on one device, be sure to sync the updated database with the cloud service. This prevents conflicts and ensures all devices have the latest version.

Uninstalling KeePassXC on Ubuntu/Debian

Open a terminal:
To begin the uninstallation process, open a terminal window.

Uninstall KeePassXC:
Use the following command to remove KeePassXC from your system:

sudo apt remove keepassxc

Remove configuration files (optional):
If you want to remove KeePassXC’s configuration files as well, use the purge command:

Clean up unnecessary packages (optional):
