In order to use the DigiD app, you would have to activate it first. And if you do not know how to do the activation, just tap on the app to open it and follow the processes in it.

Once you are done with the activation, you can now log in. And there are two ways of logging in. The first one is by using a pin code when signing in using a mobile phone or tablet. The second one is through verification, a QR code, and a pin code when using a desktop.

This app also protects your data, so you do not have to worry about any third party stealing them.
