KeePass is an encrypted password database format. It is an alternative to online password managers and is supported on all major platforms.
There are two versions of the format: KeePass 1.x (Classic) and KeePass 2.x
There are three major implementations of KeePass available in the official repositories:
- KeePass — A cross-platform password manager that has autotype and clipboard support when respectively xdotool and xsel are installed. It lets you import many formats and has many plugins.
- KeePassXC — Fork of KeePassX that is actively maintained and has additional features like browser integration, support for SSH agent, secret service, Yubikey, finger-print reader, TOTP generator and KeeShare. Also provides a CLI.
- gnome-passwordsafe — A modern GNOME password manager built on top of of KeePass.
Other lesser-known alternatives can be found in the AUR:
- keepassc — A curses-based password manager compatible to KeePass v.1.x and KeePassX. It uses
xselfor clipboard functions.
- kpcli — A command line interface for KeePass database files
- keepmenu — Dmenu/Rofi frontend for Keepass database files.
- AuthPass — KeePass compatible password manager based on Flutter. Comes with default sync suport for Gdrive, Dropbox, and WebDav.
- keeweb — A web app (online / Electron) compatible with KeePass 2.x. KeeWeb comes with default Sync support for major cloud services, Gdrive, Onedrive, Dropbox etc. No active development since release of 1.18.7 on July 18th 2021.
- KeePassX — Started as a Linux port of KeePass. keepassx2AUR uses the KeePass 2.x format, but can import 1.x databases. It also lets you import PwManager and KWallet XML databases. It does not support plugins.  No active development since 2016.

Many plugins and extensions are available for integrating KeePass to other software. KeePassX and KeePassXC do not have a plugin interface, but KeePassXC has various integrations built-in.
Plugin installation in KeePass
KeePass is by default installed at
plugin.plgx to a plugins sub-directory under the KeePass installation directory as demonstrated below:
# mkdir /usr/share/keepass/plugins # cp plugin.plgx /usr/share/keepass/plugins
keepassxc-browser for KeePassXC
keepassxc-browser is the browser extension of KeePassXC’s built-in browser integration using native-messaging and transport encryption using libsodium. It was developed to replace KeePassHTTP, as KeePassHTTP’s protocol has fundamental security problems.
The developers provide the browser extension on
- Firefox Add-ons (for Firefox and Tor Browser) and
- in the chrome web store (for Chromium, Google Chrome, Vivaldi and Brave).
Support for Firefox and Chromium forks is available. For librewolfAUR, open KeePassXC, go to Tools > Settings > Browser Integration > Advanced > Config Location:, and add
The source code and an explanation how it works can be found on GitHub, the KeePassXC developers provide a configuration guide on their website.
keepassxc-browser for KeePass
keepassxc-browser can also be used with KeePass through Keepass-natmsg Plugin from AUR (keepass-natmsgAUR) and is recommended as successor of KeePassHTTP.
KeePassRPC and Kee
Kee (GitHub repo) is a browser extension for Firefox and Chromium which integrates KeePass through KeePassRPC, a KeePass plugin from the same developers.
The KeePass plugin is available from GitHub or from the AUR (keepass-plugin-rpcAUR).
The browser extension can be found on GitHub, Firefox Add-ons and the chrome web store.
Via autotype feature
An alternative to having a direct channel between browser and KeePass(XC) is using the autotype feature. There are browser extensions which support this way by putting the page URL into the window name:
- KeePass Helper or TitleURL for Firefox
- URL in title for Chromium
- Open Keepass stores inside Nextcloud
YubiKey can be integrated with KeePass thanks to contributors of KeePass plugins. KeepassXC provides built-in support for Yubikey Challenge-Response without plugins.
Configuration with KeePass
- Configure one of Yubikey slots to store static password. You can make the password as strong as 65 characters (64 characters with leading "!"). This password can then be used as master password for your KeePass database.
- one-time passwords (OATH-HOTP)
- Download plugin from KeePass website: https://keepass.info/plugins.html#otpkeyprov
- Use yubikey-personalization-gui-gitAUR to setup OATH-HOTP
- In advanced mode untick OATH Token Identifier
- In KeePass additional option will show up under Key file / provider called One-Time Passwords (OATH HOTP)
- Copy secret, key length (6 or 8), and counter (in Yubikey personalization GUI this parameter is called Moving Factor Seed)
- You may need to setup Look-ahead count option to something greater than 0, please see this thread for more information
- See this video for more help
- Challenge-Response (HMAC-SHA1)
- Get the plugin from AUR: keepass-plugin-keechallengeAUR
- In KeePass additional option will show up under Key file / provider called Yubikey challenge-response
- Plugin assumes slot 2 is used
KeePassXC offers SSH agent support, a similar feature is also available for KeePass using the KeeAgent plugin.
The feature allows to store SSH keys in KeePass databases, KeePassXC/KeeAgent acts as OpenSSH Client and dynamically adds and removes the key to the Agent.
The feature in KeePassXC is documented in its FAQ. First configure SSH agent to start on login and make sure the
SSH_AUTH_SOCK variable is set. Then logout and log back in. Now, in KeePassXC settings, enable SSH agent integration. The
SSH_AUTH_SOCK value exposed in the UI should correspond to what you configured earlier.
ssh-add -D, therefore KeePassXC/KeeAgent cannot remove them when locking the database.  
KeePassXC contains a Freedesktop.org Secret Service integration. When enabled other programs can save secrets inside KeePassXC. While this improves overall security, it can lead to some unwanted behaviour while KeePassXC is closed, as programs that rely on their secrets to work cannot fetch them.
Tips and tricks
Disable your clipboard manager
If you are an avid user of clipboard managers, you may need to disable your clipboard manager before you launch Keepass and then re-start your clipboard manager afterwards.
KeePassXC implementations has the option to auto-clear the clipboard manager after an amount of time, enough to paste copied items.
To enable the dark theme for KeePass, install keepass-keethemeAUR. After installation, the plugin will get compiled upon starting KeePass. It can then be activated via
Tools, Dark Theme, or by pressing
