it is perfectly. but where are the guarantees that these guys will not be able to recover your password and just do not steal your money? I think there is only one option: always write down your password.
Yes it's one of the most accurate and advisable though just write down and if ever there is a back up key , then download it , or save it though ,
we can't be contented though sometimes there are some hackers too.
So be optimistic at anytime , and be aware mostly on your important stuffs.
