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.
