+# Electron
+
+[Electron](https://electronjs.org/) is an open-source framework that allows developers to build
+cross-platform desktop applications using web technologies like JavaScript,
+[HTML](/wiki/markup_language.md), and CSS.
+It combines the Chromium [browser](/wiki/web_browser.md) and Node.js.
+
+## Troubleshooting
+
+This section will focus on errors and the fixing of errors of /name/.
+
+## Linux: `Could not detect a default secure credential storage on your device.`
+
+A possible issue for Electron apps on [Linux](/wiki/linux.md) is the following error.
+
+```sh 
+not detect a default secure credential storage on your device.
+```
+
+This occurs because Electron relies on a Secret Service such as the GNOME Keyring, among others) to
+store passwords securely on the system.
+And often appears on more minimal window managers on [Xorg](/wiki/linux/x_window_system.md) or
+[Wayland](/wiki/linux/wayland.md).
+If no compatible service is running or detected, apps cannot save credentials.
+
+Using the following steps this issue can be solved.
+Firstly - if not already done - install a secret service.
+For the Gnome Keyring install the [packages](/wiki/linux/package_manager.md) `libsecret` and
+`gnome-keyring`.
+The name may differ slightly depending on the [package manager](/wiki/linux/package_manager.md)
+used.
+Afterwards make sure to run the service and enable it if not already done.
+An example for this is shown in the following command
+
+```sh 
+eval $(/usr/bin/gnome-keyring-daemon --start)
+```
+
+Finally the Electron app `<electron-app>` can be started.
+For the secure credential storage to be reachable the environment variable `XDG_CURRENT_DESKTOP`
+has to be set.
+Due to this environment variable being possibly relevant for the system-wide settings it is
+recommended to only set it for the Electron app by running the following command in a sub-shell.
+
+```sh
+export XDG_CURRENT_DESKTOP=GNOME
+<electron-app>
+```
