4 otp — manages one-time passwords
5
7 otp [-dhlor] [-f algorithm] [-u user] sequence-number seed
8
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.
