Public sector organisations offering online services are obliged to enable access for all EU citizens and businesses using their own country's 'eIDAS-recognised' log-ins.
Does your organisation have a public role? Or do you enable Dutch people and businesses to access your services using a Substantial or High-assurance-level log-in? If so, your organisation is covered by the EU’s eIDAS (Electronic Identities And Trust Services) Regulation. The regulation applies to you if, for example, your services are accessible using DigiD or eHerkenning with Substantial or High assurance (EH3 or EH4).
