We have illustrated an example where the dynamic identifier is a QR code. The code SHOULD contain a DeepLink (as within the Redirection flow) supported by the LFI which SHOULD invoke the LFI app when the User scans the QRCode.
| Rules & Guidelines |
---|---|
1 | User-facing TPPs MUST initially ask the User to identify the LFI so that the consent request can be constructed in line with the LFIs data group and/or service initiation capabilities. |
2 | User-facing TPPs MUST present Users with the authentication options supported by the LFI which in turn can be supported by the User-facing TPP device/channel (e.g. A User-facing TPP kiosk that can only support authentication by LFI mobile app). |
3 | The User-facing TPPs MUST display a code which is scannable or readable ( QRCode/NFC) by another User device. The User-facing TPP MUST present the information on how to use the code with their mobile device (e.g. scan QR code with the mobile phone camera). NOTE: The QRcode MUST be a deep link (as within the Redirection flow) supported by the LFI which MUST invoke the LFI app on scanning. |
4 | User MUST be able to easily scan the code (e.g. scan the code from the Kiosk in this instance) without much friction (like manually entering any URLs). |
5 | After the User scans the code from the User-facing TPP with a device camera, the LFI app MUST be invoked to perform the MFA. |
6 | The LFI app-based authentication MUST have no more than the number of steps that the User would experience when directly accessing the LFI mobile app (biometric, passcode, credentials). |
7 | LFIs SHOULD have an outbound redirection screen which indicates the status of the request and informs the User that they will be automatically taken back to the User-facing TPP. |
8 | LFIs SHOULD inform the User on the outbound redirection screen that their session with the LFI was closed. |
9 | For this experience it is essential that the User-facing TPPs MUST have a web page where the LFI can redirect the control back to the User-facing TPP on the second device. The User-facing TPP must confirm on this mobile web page the successful completion of the request and informs the User to continue on the other device(Kiosk/desktop) where they had started their journey. |
