Security levels

ID-porten classifies different user authentication methods into security levels of assurance. This is reflected in the acr claim for the user's JWTs issued by ID-porten.

Valid values, in increasing order of assurance levels:

Value Description Notes
idporten-loa-substantial a substantial level of assurance, e.g. MinID Also known as Level3
idporten-loa-high a high level of assurance, e.g. BankID, Buypass, Commfides, etc. Also known as Level4

To configure a default value for all login requests:

    enabled: true
      enabled: true
      level: idporten-loa-high

The default value is idporten-loa-high.

NAIS ensures that the user's authentication level matches or exceeds the level configured by the application. If lower, the user is considered unauthenticated.

For runtime control of the value, set the query parameter level when redirecting the user to login:
