If you don't fit their biometric criteria N26 will reject you.
Since I happily referred N26 to my mother, she wanted to open an account at N26. During the identification phase, just after sending a picture of her biometric passport through the mobile app, she received an email rejecting her for "security reasons". No explanation, solution, nor alternative has been proposed by N26.

The N26 support could not provide any help as they requested to discuss with my mother (not with me) directly from her N26 app account — that she has been rejected to open! Very disappointed, she finally gave up the idea of opening an account at N26.

I would advise — if you don't match N26 biometric criteria – not to open your account here otherwise you could be bluntly turned away.
