No, not at all.
There are various ways to use DieFi and register information; it is totally up to the user what they want to register. If someone is uncomfortable typing in their seed phrases, there are other options to benefit from DieFi. I.e. We have a “Cold Storage” feature where users can register information about their Ledger/Trezor or physical steel devices.
Users can add comments to the beneficiaries on ie. where to find the devices, what to do and ie. the PIN code for the devices.
Also, you can use DieFi (for free) if you just want to use it as your dashboard/ one-stop platform for all your crypto information. You will need to upgrade if you decide to add beneficiaries/ use the Dead Man's Switch feature.
