The problem seems to be that no German bank I know of support 2FA for login purposes which is what that list tracks[0] (although they don't state that clearly – it took me a few minutes to track that down)
But listing "Sparkasse" as one German bank is misleading as there are 400 independent banks sharing that brand with different policies. They use at least a few different backends for their online system although there seemed to have been some consolidation in recent years.
