As policy flows down from law and/or regulation (e.g. GDPR) our individual privacy concerns give rise to demands on improving accessibility, awareness and comprehension, the topic of eConsent is becoming more prevalent. We provide a critical voice by considering, but also challenging, the underlying assumptions that the status quo of eConsent design and implementation is appropriate for all people in society. By answering "what eConsent characteristics are prevalent in the context of dementia applications?", this paper identifies that the "one size fits all" ethos for eConsent is not applicable in every context. As a result, a taxonomy that depicts the multifaceted concept of eConsent is proposed. It makes us aware of the different ethical, legal, social and technical implications of ICT use and provides an opportunity to create discourse in this area. It argues that future research examining the effectiveness of innovative ICTs must take the eConsent process into account.
