There is already a tool for recovering accounts on SteemWorld: https://steemworld.org/account-recovery

Important to know is that only the recovery account can start a recovery request. After the recovery account started the request, the account to be recovered needs to confirm it (can also be done on that page).

So, if you want to make use of that feature in future, you first need to change your recovery account to someone you trust and who is capable of doing the mentioned steps.

Changing the recovery account can be done on the Dashboard page (Account Details -> Account -> Change Recovery Account).
