Is it safe to enter my online banking access data at Qwist?

Yes. As a payment institution, Qwist is supervised by the financial supervisory authority BaFin and is therefore always subject to various inspections by different auditors with regard to IT security and data protection (see also above under the category > 1. About Qwist the question: Is Qwist secure?). Your online banking access data already benefits from special protection by law and as part of the implementation of all requirements.
