That is why I said this is just nothing but previous-era coinbase wallet, using email to register, and password/PIN for login which means custodian wallet, and that is not preferred for storage at all.
I see, i initially though what OP wanted to show directly mentioned on https://z.cash/ecosystem/edge-wallet/. Although Edge wallet doesn't call their feature as "Zero-knowledge proof authentication".
Threshold signature-based authentication provides a great alternative to already popular multi-sig wallets. As mentioned in this article https://www.blockdaemon.com/blog/why-threshold-signature-wallets-are-better-than-multisig-wallet-top-5-reasons, it does add more value. I'm only concerned with this approach because you still would have to manage and communicate multiple parts of the key, which may cause delays in performing transactions.
Reason 1-3 already solved with Taproot, see link i mentioned above. While AFAIK reason 4-5 can't be solved with Taproot. Although i expect changing to value of n and m on n-of-m (stated on reason 5) rarely happen in practice.

So the scammers can use it to steal more money from us like bank accounts, credit cards, and what else?
