Each user can have multiple deviceId values, each correlating to a different Wallet (NCW) in Fireblocks. Each deviceId represents an entity that stores an end-user key share.
Hi,
i have a question. Does it mean, every wallet can only have one single deviceId , or does it mean one wallet, can have multiple deviceID , so user can login on multiple device ?
sorry, my further question is , if the user have changed the device they use / using multiple devices, so for every devices, must have a different wallet ?
or this is the usecase of backup & recovery method?
Ideally you would disable the deviceId no longer inuse by setting enabled to false.
Regarding Backup & recovery the Fireblocks Non-Custodial Wallet (NCW) provides a backup and recovery mechanism to make sure that users can recover their keys even if their NCW device is lost or damaged.
