SCA-RTS 90-day reauth Implementation

Which date are you planning on implementing the SCA reauthentication exemption?


20th September 2022

What is your approach to token management to enable application of the reauthentication exemption? (see link to FCA guidance)


AIS consents created after the implementation of the changes will remain valid until the Consent Expiry Date, if set. They will not normally need to be reauthenticated.


Existing AIS consents will require a final reauthentication, at which point they will remain valid until the Consent Expiry Date, if set. No further reauthentication will normally be required.


There are scenarios where a reauthentication may be necessary, including but not limited to:

  • Suspected fraud or unauthorised access

  • Where a Nationwide Member has revoked the access via our digital and/or mediated channels
