The basic tools of digital communication between citizens and the state are eID, eMailbox and eSignature. Read more in our guide to get started with electronic communication with the stateOpens in a new window.
To log in and access e-services, you need an ID card with an electronic chip along with a personal security code (BOK), a smart card reader, and software installed on your computer. Before installing the applications, please read the information in the “How to start communicating with the state electronicallyOpens in a new window” section.
On this page, you will find a login application (for eID) and a qualified electronic signature (KEP) application suite.
You can create and validate qualified electronic signatures on Apple macOS, Linux, and MS Windows operating systems using the free QES and aQES applications provided by the National Security Authority (available for Apple macOS, Linux, Windows 64/32-bit platforms)Opens in a new window. The QES and aQES applications also allow web form signing if the website triggers signing via an HTTP POST call. Read more in the QES guide (webnode.sk)Opens in a new window.
The justification for requiring software installation and information for integrators are available on a separate page.Opens in a new window
You can purchase a smart card reader at electronics stores. The readers are plug-and-play, so they do not require additional driver installation.

If the relevant public authority portal has integrated and enabled the launching of KEP components on its website via the D.Launcher v2 application, the Java KEP components will download to your PC automatically.
The D.Launcher v2 application provides not only automatic installation and updates for Java platform KEP components and the required Java Runtime Environment (JRE), but also its own automatic updates, while resolving several technical issues present in the older D.Launcher v1 application by leveraging modern technologies.
This application is used to view data structures designed for electronic data exchange, particularly electronic submissions, forms, and their attachments intended for communication with the public administration of the Slovak Republic.
Java KEP components have been tested only with the explicitly listed web browser versions.

The Java components for qualified electronic signature (KEP) have been tested only with the explicitly specified versions of web browsers. Pozn.: beh webového prehliadača v "sandbox" režime – napr. systém Snap alebo Flatpak, nie je podporovaný.
To run and use individual applications for qualified electronic signature in web browsers, it is necessary to install the D.Launcher v2 application. A newer version of the D.Launcher application, v2.x, together with the new version of the D.Bridge JS libraries v1.5 and the corresponding D.Bridge 2 web browser extension, also enables automatic installation and updates of KEP components on the Java platform, the required Java runtime environment (JRE), as well as its own automatic updates. At the same time, it resolves several technological issues present in the older version of the D.Launcher v1 application by using more modern technologies.
We would like to inform you that support for the D.Launcher v1 application has been discontinued by the application provider, and therefore this application has been removed from the .NET component package for QES D.Suite/eIDAS. Installers of the D.Launcher v1 application for supported operating systems will be provided by the D.Launcher v1 provider only to administrators of the relevant specialized portals that have not yet implemented integration of client QES components via the D.Launcher v2 application and the D.Bridge 2 extension. These installers will be provided only upon request and exclusively to support their users during a transitional period until December 31, 2025.
For help with installing the extension, follow the D.Launcher v2.x User Guide, Chapter 3.3.Opens in a new window

The application is used for viewing data structures used for electronic data exchange, in particular electronic submissions, forms, and their attachments intended for communication with the public administration of the Slovak Republic.
These versions of D.Suite/eIDAS KEP client applications are intended only for special use, such as signing large PDF files (several hundred MB).
For standard use of qualified electronic signature applications on MS Windows operating systems (both 32-bit and 64-bit), we recommend installing the 32-bit KEP application versions available in the MS Windows section.
To launch and use individual qualified electronic signature applications in web browsers, you must install the D.Launcher v2 application. The newer version of D.Launcher (v2.x), together with the new D.Bridge JS library version (v1.5) and the corresponding D.Bridge 2 web browser extension, also enables automatic installation and updating of Java platform KEP components and the required Java Runtime Environment (JRE), as well as its own automatic updates, while resolving several technical issues present in the older D.Launcher v1 by leveraging modern technologies.
Please note that support for the D.Launcher v1 application has been discontinued by the developer, and it will no longer be available on the www.nove.slovensko.sk portal or for users of the GNU/Linux operating system. Installers for D.Launcher v1 for supported operating systems will now only be provided by the developer upon request to administrators of affected specialized portals who have not yet implemented the integration of client KEP components via D.Launcher v2 and D.Bridge 2 extension, solely to support their users during the transition period ending 31 December 2025.
To install the extension, follow the D.Launcher v2.x User manual, Chapter 3.3.Opens in a new window
To work in web browsers that do not support ActiveX or NPAPI technologies, such as MS Edge, Mozilla Firefox, or Google Chrome, you must install the D.Launcher v1.x application as well as the new D.Launcher v2.x, both of which are included in the D.Suite/eIDAS KEP client application suite.
