Enable cross-border identification
If identification is required for using the services, it must be possible to identify yourself across borders using eIDAS identification.
A cross-border client can also be offered an alternative way of using e-services, such as their own eForm that does not require identification.
However, eIDAS identification is mandatory if the e-service is connected to the OOTS.
You can get more detailed instructions on eIDAS identification from the Digital and Population Data Services Agency’s Suomi.fi Palveluhallinta.
