First of, is 1password comupter specific? I mean could someone download 1password on another computer and acces my logins if they had my masterpassword?
Second question, what do I do if my computer crashes? I have synced it with dropbox so am I good to go then? Does it work like then I just reinstall 1password and use the backup keychain I have stored in dropbox and everything is like it used to be?
