Article 32(3) of the RTS prohibits the creation of obstacles. Paragraph 15 of the EBA Opinion on obstacles (EBA/OP/2020/10) specifies that the authentication journey should not create "unnecessary friction or add unnecessary steps".

When a PSU provides consent to an Account Information Service Provider (AISP) for access to their payment account information, this is typically a single, holistic act of consent for the scope of the AISP's service. However, some ASPSPs, during the redirection journey, present the PSU with a consent screen that breaks this single consent down into multiple, separate checkboxes. The PSU is then required to manually tick each box (e.g., one for 'account details', another for 'account balance', and a third for 'transaction history') to proceed.

This practice creates confusion, as the PSU has already provided their consent to the AISP. It also adds several manual steps to the process. It is unclear if this design pattern, which dissects a single user intent into multiple required actions, is compliant with the RTS.
