Good job idd! Last month I wrote a request for the programmers in the Steemit community: https://steemit.com/hardwarewallet/@michiel/hardware-wallets-new-and-incredible-interesting-devices-idea-for-steemit
I am not a coder, so I can only spread the idea. Hope someone will pick it up and create the possibility to secure a Steemit account for 100%
