AuthenticationApproach

Authentication approaches that can be applied. REDIRECT: the PSU is redirected by the TPP to the ASPSP which processes identification and authentication DECOUPLED: the TPP identifies the PSU and forwards the identification to the ASPSP which processes the authentication through a decoupled device EMBEDDED-1-FACTOR: the TPP identifies the PSU and forwards the identification to the ASPSP which starts the authentication. The TPP forwards one authentication factor of the PSU (e.g. OTP or response to a challenge) NONE: there is no need for the PSU to authenticate
