It is not possible to use the DigiD app within the MyQii app. Currently, only government organizations are permitted to use the DigiD app. The government is working on legislation to change this. Once the law is approved, we will integrate the DigiD app into the MyQii app.
In the MyQii app, you can only log in using your DigiD username and password. If you have forgotten these, you can view your username and change your password via My DigiD.
