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 performed 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 supplied
sequence-number and seed.
-u
- To choose a different user to set one-time passwords
for. This only works when running
otp
as
root.
