p Options:
p l -tag -width Fl t Fl n No timeout is used. The terminal will be locked indefinitely or until current challenge is met. t Fl p 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 challenge to which they may respond with a six-word S/Key one-time password. t Fl t Ar timeout The time limit (default 15 minutes) is changed to .Ar timeout minutes. .El .Sh SEE ALSO .Xr skey 1 .Sh HISTORY The .Nm command appeared in x 3.0 .
