It is important to prepare your users in time, in order to allow them to prepare for logging into your services with eHerkenning. As it takes some time to request and receive the eHerkenning login means, they will need a timely notice. So it is important to ensure effective internal and external communication.
eHerkenning provides a manual with several steps explaining how to best communicate the upcoming switch to eHerkenning for your service, see https://www.eherkenning.nl/communicatie.
Required graphics (the logo, login buttons, and Levels of Assurances) for eHerkenning can also be downloaded.
