My system disk is full encrypted with luks. My Ubuntu logs in automatically, because I am the only user. But I still need to unlock my Gnome Keyring and I wonder, if there is any sense for that. Because I always unlock the keyring when I login, so it is always accessible while the computer is running. What if I would set the password to blank, what could be the security risks?
The only reason I can imagine is, if I would do any stupid like backing up the keyfile to a non encrypted device or sending it by mail, it would still be password locked. But I shouldn’t do something like that anyway.
