Katso sign-in through Suomi.fi starting 19 September 2017Tax Administration Bulletin, 9/14/2017
The old “tunnistus.fi” is to be replaced by the new sign-in service of Suomi.fi. The change will be made Tuesday 19 September between 6 and 7 am.
Secure sign-in is necessary for a number of Katso functionalities in which online users must identify themselves (including Master User Setup, reopening a locked Katso ID, and upgrading a Sub-ID). The visual appearance of the sign-in menu will be similar to Kela’s start menu. The menu also contains a new sign-in option: Mobile certificate.
The changes do not require any action on the users’ part.
