Also for extra security you can add Account Restoration Code to get your account restored by Admin.
Account Restoration Code Help you restore account in situation:
- your email is not able to receive emails from admin or it's forgotten
- you are not able to restore account password with change password function
It can be also used to restore vault password by Admin. When you register, try to make it difficult to hack (in example: ArdfR9534H). And try to remember that.
