Is MinID not an option in ID-Porten?
When you log in to a service that requires the highest level of security, you can not use MinID.
This includes login to your health information or services where there is sensitive information about you.
If you want to sign an agreement, you also need to log in with the highest level of security; BankID, BankID on mobile, Buypass, Commfides.
NB! It is the service owner who determines the safety level you have to use when you log in.
