# Authentication
The most common scenario where to use DigiD is end-user authentication with the services of the public administration or with organisations providing public services in the Netherlands. DigiD authentication requires the BSN of the end-user.

Note
The flow in this section shows an example of authentication performed on the same (mobile) device. A flow for authentication across multiple devices, such as going from laptop to app, consists of more steps.
Imagine a situation where an end-user wants to access a restricted section on your mobile application using DigiD.
To log in using DigiD for authentication:
- The end-user locates the DigiD login button on your application. Clicking the button opens the DigiD app automatically.
- The end-user enters the PIN code to access the DigiD app.
- The end-user views the confirmation screen in the DigiD app that shows the icon and name of your application. After clicking "Log in", the DigiD app switches back to your application.
- Once the authentication process is complete, the end-user gains access to your application.
The flow would look like:
