.Sh DESCRIPTION
|
|
.Nm Lock
|
|
requests a password from the user, reads it again for verification
|
|
and then will normally not relinquish the terminal until the password is
|
|
repeated.
|
|
There are two other conditions under which it will terminate: it
|
|
will timeout after some interval of time and it may be killed by someone
|
|
with the appropriate permission.

A password is not requested, instead the user's current login password
|
|
is used.
|
|
If the user has an S/Key key, they may also use it
|
|
to unlock the terminal. To do this the user should enter "s/key"
|
|
at the unlock "Key:" prompt. The user will then be issued an S/Key
|
|
challange to which they may respond with a six-word S/Key one-time
|
|
password.
|
|
.It Fl t Ar timeout
|
|
The time limit (default 15 minutes) is changed to
|
|
.Ar timeout
|
|
minutes.
