Hey very cool @arcange

Though I did want to clarify something for readers.

your private keys have been lost, leaked or stolen and your account and funds are at risk.

Account recovery CAN NEVER WORK if you do not have a previous working Owner key. This is how the recovery process works.

The recovery account is unable to take over your account at will due to the fact that they need a working owner key to process the account recovery.

@someguy123 has a little more details and technical info about the process https://peakd.com/steem/@someguy123/how-the-steem-account-recovery-works-and-why-your-trustee-can-t-steal-your-account

If you get your password stolen or hacked and someone changes your accounts owner key, you can use the hacked owner key to take back control of your account.

If you lose your password altogether, you are screwed.

YOU CAN NOT RECOVER AN ACCOUNT IF YOU LOSE YOUR PASSWORDS AND DO NOT HAVE ANY BACKUPS FROM PREVIOUS PASSWORDS

(PS: it is up to your recovery account to ask for whatever info they want to verify you are the rightful account owner. This is why it's usually good to have some trusted user or friend act as recovery)
