its pretty scary if you think about it.
you can have thousands of dollars and someone can steal it all
and nobody can help you
i just hope my 15 character alphanumeric password to all my bitcoin related accounts is enough =D
ideally, you should use different passwords for every account. have you considered using keepass2 or another similar secure password manager?
you can keep the keepass2 passwords and such encrypted on a usb dongle around your neck or on your neckchain, but that's meant as a backup, in case you lose the computer with keepass2 installed, or in case you need to use a school, work, or library computer.
but ideally, you'd use something like that. a single password across many bitcoin websites isnt exactly ideal. just saying.
