16 login. The program will ask you to enter a secret pass phrase; enter a
17 phrase of several words in response. After the S/Key database has been
18 updated you can login using either your regular UNIX password or using
19 S/Key one-time passwords.
21 When logging in from another machine you can avoid typing a real
22 password over the network, by typing your S/Key pass phrase to the
24 command on the local machine: the program will respond with
25 the one-time password that you should use to log into the remote
26 machine. This is most conveniently done with cut-and-paste operations
27 using a mouse. Alternatively, you can pre-compute one-time passwords
30 command and carry them with you on a piece of paper.
