NAME¶
otp
—
manages one-time passwords
SYNOPSIS¶
otp |
[-dhlor -f
algorithm-u
user |
DESCRIPTION¶
Theotp
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.
