The solutions I've used are normally 2fa, and the alternative was sign a paper,scan it and email it which is less secure

As I understand, 2fa will bind your document to the information system that was used to share document. Ex: Court would ask evidence for second part identity event if 2fa used.

Have you ever faced these problems? I yes, how do you tackle these problems?
