On a default Ubuntu with the root account locked, selecting "(recovery
mode)" will drop one straight to a root shell, without requiring a password.
The idea behind this is simple; the only time time that somebody really
needs to do some form of recovery, is when the machine is in a very bad
state. Handling a really broken machine/forgotten password is a stressful
experience---the least that can be done is to optimise the recovery
operation by getting a user what they need, fast and efficiently.
If the user /has/ altered the default setting and set a root password, then
selecting "(recovery mode)" will require that shared root password to be
entered.
The set root password can be disabled again with:
sudo passwd -l
