🌙 KeePass Dark Mode – Dark Theme for KeePass 2.x

💡 Why KeePass Dark Mode?

The standard KeePass interface is bright and designed for daytime work. Anyone who opens their password manager in the evening or at night knows the problem: a white window in a dark room. KeePass Dark Mode solves this with a calm, dark color palette for the entire interface – menus, lists, dialogs and the entry editor.

• 🌑 Dark theme – calm, modern colors across the whole KeePass interface
• 🎨 Five themes – Standard, Windows 11, Dracula, Colorblind and High Contrast, switchable from a dropdown
• ⌨️ Hotkey – STRG+T toggles the theme, freely configurable
• 🖌️ Theme editor – create your own color worlds in a GUI, without editing text files
• 🔧 Automatic detection – follows the Windows color scheme: active in dark mode, off in light mode
• 🎨 Windows accent – optionally takes over the Windows accent color for highlights
• 🔔 Update hint – shows a new version directly in the Tools menu
• 🪟 Flicker-free – dialogs and text fields are built dark before they paint their first frame
• 🖥️ Native dialogs – message boxes and windows get a dark title bar

🚀 Installation

1. Download KeePassDarkMode.plgx from the release page.
2. Copy the file into the plugin folder:

3. Restart KeePass – done. Switch the theme with STRG+T or under Tools → Dark Theme.

The built-in theme editor creates your own color worlds in no time. Own theme files (.ini) simply go into the plugin folder – they appear automatically under Tools → Options → KeePass-DarkMode. Five themes ship with the plugin:

🔧 Troubleshooting

Clear the plugin cache

After an update, an outdated plugin cache can cause loading problems. Delete %LOCALAPPDATA%\KeePass\PluginCache\ (with Pleasant PPS: %LOCALAPPDATA%\PleasantKeePass\PluginCache\) and restart KeePass.

Some areas stay bright

KeePass uses classic Windows controls that can only be recolored to a limited extent. Individual spots (e.g. certain dialogs and system menus) can stay light – usable in everyday life, but not uncompromising pixel-perfect theming.

🧩 Compatibility

• KeePass: 2.4x and newer (built against 2.42, runs with current versions)
• Windows: 10 and 11
• .NET Framework: 4.5 or newer

🛠️ Development

The plugin is written in C# and decorates the native KeePass controls – among them the entry list (ListView), the entry editor (RichTextBox), menus and known system colors. Build under Windows with:

msbuild KeePass-DarkMode.sln /p:Configuration=Release

The .plgx package is then created with build.cmd. Important when packaging: KeePass takes the BaseFileName from <AssemblyName> of the .csproj and expects the plugin class <AssemblyName>.<AssemblyName>Ext from it – file name, assembly name and class name must match.
