Finnish Authenticator Identification Service

The foreign citizen identification service, or the Finnish Authenticator Identification Service, allows foreigners to use Finnish public administration e-services that have introduced the identification using the Finnish Authenticator application.

Because identification using the application replaces the Katso service which will be discontinued, it is intended only for foreigners who have used Katso identification and who do not have a Finnish personal identity code and who cannot use Finnish identification tokens.

In the Finnish Authenticator Identification Service, a foreigner registers his or her foreigner’s user identifier (UID) and verifies his or her identity using the Finnish Authenticator application. In connection with this first identification, the user will take a photo of oneself, as well as of his or her passport or national ID card. The identification service will confirm the person’s identity if the photo and the information in the identity document match. 

After registration and initiating use of the application, foreigners can log in to the e-service using their user identifier or email, password and application PIN.

The provision of the Finnish Authenticator Identification Service by the Digital and Population Data Services Agency is based on the Act on the Population Information System and Certificate Services Provided by the Digital and Population Data Services Agency (661/2009) and the Act on Central Government’s Joint e-Service Support Services (571/2016). Identification has been implemented in connection with Suomi.fi e-Identification. The Finnish Authenticator identification service is not a strong electronic identification service, but by using the application, the user can show proof of his or her identity when logging in to an e-service.
