Katso identifiers and the Katso service website

If you have a Katso ID and password, you can log in to various official e-services as a representative of your business. In addition to business companies, many other corporations, public organisations (such as municipalities) and estates of deceased persons can use Katso. As an alternative, you can give an authorisation electronically to someone else – typically, an accountant or an accounting firm – to act on your behalf.

Katso is a means of strong identification as it consists of a user ID, a password and a one-time password. Katso identifiers are free of charge.

When you log in to the Katso website, you can manage your Katso ID, change your password, print out a list of passwords, etc. In addition, if you are a Master User at your organisation, you can create Katso sub-IDs for your employees and manage them. You can also grant and receive authorisations.
