Password authentication of the SSH client requires a user id and a password.
This user id and password must correspond to an actual user id and password on the host on which the SSH server resides.
For example, suppose that the host
on which the SSH server resides is
host 9.27.63.30
,
and suppose also that there exists on this host
a user id user1
with the password user1pass
.
In this situation,
an SSH client could log on to the host
by specifying
the user id user1
and the password user1pass
.
