The diagram below depicts an overview of the flow, taking place during the creation and authorisation of a payment, including who plays what role. The respective banks responsibility is limited to the actions happening between the TPP and ASPSP. All parts of the flow are described except the SCA, which has been depicted below.
MitID - SCA authentication flows
In relation to payments, the SCA process is confined to the MitID process and is implemented 2-factor authentication.
Upon completion of the SCA process, the PSU will be redirected to the TPP-Redirect-URI. If an error occurred, the PSU will be redirected to the TPP-Nok-Redirect-URI.
Please refer to the following document describing the full MitID SCA authentication flows:
