Security
Scenario 1: If you have only created a wallet on one card and never backed it up:
Unfortunately, if you don’t have any backup cards for your wallets and you lose the primary card, you will lose access to all your digital assets. Additionally, anyone who obtains your card will have full access to your assets. Therefore, it is crucial to keep your card secure, though we highly recommend never relying solely on one card without backups.
Scenario 2: If you use 2-card or 3-card set, and you lost one of the cards:
During backup, you were prompted to set an access code for your 2-card or 3-card set. Hence, even if someone gains access to one of your cards, they require the access code to access your digital assets in the wallet. As long as your access code has not been leaked alongside, your assets should remain secure. However, to prevent any chance of others guessing your access code and jeopardising your assets, we recommend you promptly use any remaining cards to transfer your digital assets to a new secure address.
Additionally, after transferring the digital assets to another secure wallets, you have the option to reset the remaining card(s) to factory settings and use them as a blank new card.
Scenario 3: If you use 3-card set, and you lost two of the cards:
Losing two cards simultaneously presents a challenge. With 2 cards, even without knowledge of the access code, one can Forget and Reset the access code to the cards and gain access to your digital assets. In such a scenario, use your remaining card immediately to transfer your digital assets to another secure wallet.
Scenario 4: If you use 2-card or 3-card set, and you lost all of the cards:
Unfortunately, if you lose all your cards, you will completely lose access to your digital assets with no means of recovery. Therefore, it's crucial to safeguard your cards and ideally keep them in different locations.
Important Note: It is crucial to have backup card(s) and decide the number of backup cards you want in the beginning, as this backup process can only be done once. It's also important to note that post-backup, any individual in possession of a physical card and its access code has the capability to "remove" any of the cards by resetting them to factory settings, effectively decreasing the total count of operational cards.
