NAME

     otp - manages one-time passwords

SYNOPSIS

     otp [-dhlor] [-f algorithm] [-u user] sequence-number seed

DESCRIPTION

     The otp program initializes and updates your current series of one-time
     passwords (OTPs).

     Use this to set a new series of one-time passwords.  Only perform this on
     the console or over an encrypted link as you will have to supply your
     pass-phrase.  The other two parameters are sequence-number and seed.

     Options are:

     -d      To delete a one-time password.

     -f      Choose a different algorithm from the default md5.  Pick any of:
             md4, md5, and sha.

     -h      For getting a help message.

     -l      List the current table of one-time passwords.

     -o      To open (unlock) the otp-entry for a user.

     -r      To renew a one-time password series.  This operation can be per-
             formed over an potentially eavesdropped link because you do not
             supply the pass-phrase.  First you need to supply the current
             one-time password and then the new one corresponding to the sup-
             plied sequence-number and seed.

     -u      To choose a different user to set one-time passwords for.  This
             only works when running otp as root.
