You can't actually access your 1pw vault from wherever if you don't have an existing authenticated device or a copy of your secret key. That's intended to provide added security in case your master password is compromised. So to guard against the house burning down situation you need to either keep a printout of the secret key somewhere else (friend's house, bank box, etc.) or save it somewhere (secure) online where you can get it without using 1pw.
