What is a Merisaukko ID?
One account for every Merisaukko service, such as Ohjuri.
Updated 5 November 2026
With a Merisaukko ID you sign in to every Merisaukko service. The account lives at https://id.merisaukko.fi.
- One sign-in: once you're signed in to your Merisaukko ID, you get into the services without signing in again. Signing out also signs you out of the services on the same device.
- Security in one place: your password, passkeys and two-step verification are set once and protect every service.
- Services page: the account's front page lists all Merisaukko services, opens them and lets you request deletion of your data from a service.
Creating an account #
For now, Merisaukko IDs can only be created by invitation. The invitation link is valid for 7 days. If it has expired, ask for a new one.
What services receive #
When you sign in to a service, it receives a permanent identifier, your email address, display name, username and language from your Merisaukko ID. Your password is never shared with services.
