BankID Secure start in Lime products

The Swedish e-identification service “BankID” sharpens the requirements on starting an identification or signing process in their applications in order to increase the security and prevent risk of fraud. Details about the requirements, reasons behind and an FAQ is available on

Lime Technologies will build a new version of Lime BankID API and JavaScript application that fully supports “Secure start”. It will no longer be possible to start a BankID identification/signing in someone's BankID app just by providing the personal identity number. Instead, the user can choose to autostart the BankID app on the same device, as where it is requested, or on another device by scanning the animated QR code. The identification/signing can still be locked to a specific personal identity number, for example in authentication or signature processes.
