Vahvistus (Strong Authentication)
Finland's strong electronic identification system using bank IDs, mobile certificates, or ID cards to access digital services securely.
Detailed explanation
Finland is one of the most digitized societies in the world, and strong authentication is the gateway to nearly all online services. When a service requires you to "tunnistaudu" (identify yourself), you use one of the approved strong authentication methods to verify your identity.
Bank ID (pankkitunnukset) is the most widely used method. When you open a Finnish bank account, you receive online banking credentials (username, password, and one-time codes or a mobile app authenticator). These credentials work not only for banking but also for logging into government services, healthcare portals, tax services, and many private services through the Finnish Trust Network (Suomi.fi tunnistus). Mobile certificate (mobiilivarmenne) is a SIM-card-based identification available through Finnish mobile operators. The Finnish ID card (henkilökortti) with a chip can also be used with a card reader for electronic identification.How it affects expats
