Online Bank Identification (TUPAS) is an identification method provided by several Finnish banks within the framework of the Finnish Trust Network (FTN). Its main purpose is to serve as a strong identification method for citizens in Finland. Online Bank Identification allows businesses and organizations that provide Internet services to authenticate their customers with bank identification credentials issued by the Finnish online banks offering the service. Each bank authenticates its customers with the same bank-specific identifiers that the customer uses in the bank’s own services. The following banks are members of the TUPAS cooperation: Handelsbanken, Nordea, OP Bank Group, Danske Bank, Aktia, Saving Banks, POP Bank, Bank of Aaland, S-bank and OmaSP.
Please note that technical TUPAS protocol will no longer be considered suitable for a strong identity method’s API after 2019-09-30. Banks will start to use new technical protocols (SAML2 or OIDC) for online identification before that date.
