Hi @asus78 we are well aware of KZen (ZenGo company), as a matter of fact our engineers talk from time to time. We are using similar threshold-signature technology for MPC, difference is mainly on some process transparent to the user and how we treat backups. They encrypt the key material using a facemap (think “face ID”) and upload it to your Google account or iCloud, we display the 12 words and let the user backup as they wish.
Regarding access, for on-boarding and use on mobile the process will be as fast, the difference is when accessing the Nash platform from the web. For that there is a bit more complication so we can’t go away passwords just yet (we might in mid term).
