oottpp - manages one-time passwords
SSYYNNOOPPSSIISS
oottpp [--ddhhlloorr] [--ff _a_l_g_o_r_i_t_h_m] [--uu _u_s_e_r] _s_e_q_u_e_n_c_e_-_n_u_m_b_e_r _s_e_e_d
DDEESSCCRRIIPPTTIIOONN
The oottpp 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 _s_e_q_u_e_n_c_e_-_n_u_m_b_e_r and _s_e_e_d.
Options are:
--dd To delete a one-time password.
--ff Choose a different _a_l_g_o_r_i_t_h_m from the default md5. Pick any of:
md4, md5, and sha.
--hh For getting a help message.
--ll List the current table of one-time passwords.
--oo To open (unlock) the otp-entry for a user.
--rr 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 _s_e_q_u_e_n_c_e_-_n_u_m_b_e_r and _s_e_e_d.
--uu To choose a different _u_s_e_r to set one-time passwords for. This
only works when running oottpp as root.
