Authentication

The Authentication API is used to verify the identity of users who sign up and log in to online services. This is done by using electronic IDs (eIDs). eIDs are provided by banks and other trustworthy institutions, which allows you to confirm that your user is who they claim to be. The Authentication API is useful for both onboarding new users and authenticating existing ones. In both cases, you just have to ask them to verify their identity using one of the available eID methods.

You can onboard and authenticate your users using our REST API or the OpenID Connect standard.
