Signicat Authentication is an authentication platform that provides access to multiple identity verification methods through a single integration point. The platform supports various authentication methods including biometric scanning (TouchID, FaceID, fingerprint), electronic identities (eIDs) such as BankID and MitID, SMS and email one-time passwords, and passkeys. The solution offers authentication methods across different European regions, including Nordic countries (Norwegian BankID, Swedish BankID, MitID, Mobiilivarmenne, Freja eID), DACH region (Neuer Personalausweis), Benelux countries (DigiD, iDIN, itsme, eHerkenning), and other European nations (SPID, Smart-ID, Estonian ID). The platform includes MobileID, a mobile authentication solution that provides banking-grade security for transactions and sensitive actions. Signicat Authentication is PSD2 compliant and supports Strong Customer Authentication (SCA) requirements for mobile applications and websites. The platform provides different levels of assurance aligned with eIDAS standards, ranging from low (OTPs) to substantial (eIDs) to high (biometric scanning). Integration options include OpenID Connect (OIDC), SAML 2.0, and REST API. The platform is designed for developers with API-based integration and includes documentation, quickstart guides, and code examples.
