The Katso service will be replaced by Suomi.fi e-Identification and Suomi.fi e-Authorizations. In January 2021, it will no longer be possible to use the Katso ID for identification and the roles and authorisations in the Katso service will no longer be valid.
More time, up to 30 April 2021, is now available for the Tax Administration’s Katso IDs and Katso authorisations. As for Finnish Customs, secure login with Katso will continue until the end of February.
Because Katso will be withdrawn, users should start using Suomi.fi – a secure login service maintained by the Digital and Population Data Services Agency (DVV).
