NAME

4     otp — manages one-time passwords
5

SYNOPSIS

7     otp [-dhlor] [-f algorithm] [-u user] sequence-number seed
8

DESCRIPTION

10     The otp program initializes and updates your current series of one-time
11     passwords (OTPs).
12
13     Use this to set a new series of one-time passwords.  Only perform this on
14     the console or over an encrypted link as you will have to supply your
15     pass-phrase.  The other two parameters are sequence-number and seed.
16
17     Options are:
18
19     -d      To delete a one-time password.
20
21     -f      Choose a different algorithm from the default md5.  Pick any of:
22             md4, md5, and sha.
23
24     -h      For getting a help message.
25
26     -l      List the current table of one-time passwords.
27
28     -o      To open (unlock) the otp-entry for a user.
29
30     -r      To renew a one-time password series.  This operation can be per‐
31             formed over an potentially eavesdropped link because you do not
32             supply the pass-phrase.  First you need to supply the current
33             one-time password and then the new one corresponding to the sup‐
34             plied sequence-number and seed.
35
36     -u      To choose a different user to set one-time passwords for.  This
37             only works when running otp as root.
