BankID is Norway's digital identity with ~4 million active users. 4b2b supports BankID 2.0 OpenID Connect for secure login, BankID signing for electronic contracts, and PSD2 SCA (Strong Customer Authentication) in banking-related flows. Operator-agnostic.
You run a law practice and want legally valid login for clients.
BankID login provides qualified electronic identification (QEI) under eIDAS. Timestamp logging + signature archived for 10 years per Accounting Act + Bookkeeping Act.
A client signs a contract — how strong is the binding legally?
BankID signing is a qualified electronic signature (QES) under eIDAS — same legal effect as a handwritten signature. Audit trail with fingerprint hash + timestamp.
You integrate with DNB Open Banking — PSD2 SCA requires step-up authentication.
The platform triggers BankID as an SCA factor before transactions. The token from BankID can be forwarded to DNB Open Banking API as "X-Authorization-Headers".
Mobile BankID fails — what fallback is available?
BankID on Mobile + BankID via code chip both supported. The platform offers both on failure or for older users without a smartphone.
The entire 4b2b ecosystem is built for the Norwegian market — from EHF invoicing to SAF-T export and A-melding. You don't need to integrate against Altinn yourself.
