I understand that you are satisfied with simple similarity, but this still means that you have to define the conditions under which you would regard two words as similar.
For example, you could see two words as similar, if they just differ in upper/lower case spelling. This would be easy to implement.

pam_otpw
PAMOTPW(8) System Manager's Manual PAMOTPW(8)
NAME
pam_otpw - verify one-time passwords
SYNOPSIS
pam_otpw [ arguments ]
DESCRIPTION
OTPW is a one-time password authentication system. It compares entered passwords with hash values stored in the user's home directory in
the file ~/.otpw. Once a password was entered correctly, its hash value in ~/.otpw will be overwritten with hyphens, which disables its
use in future authentication. A lock file ~/.otpw.lock prevents that the same password challenge is issued on several concurrent authenti-
cation sessions. This helps to prevent an eavesdropper from copying a one-time password as it is entered instantly into a second session,
in the hope to get access by sending the final newline character faster than the user could.
Both an authentication management and a session management function are offered by this module. The authentication function asks for and
verifies one-time passwords. The session function prints a message after login that reminds the user of the remaining number of one-time
passwords.
ARGUMENTS
debug Turn on debugging via syslog(3).
nolock Disable locking. This option tells the authentication function of pam_otpw.so to ignore any existing ~/.otpw.lock lock file and not
to generate any. With this option, pam_otpw.so will never ask for several passwords simultaneously.
AUTHOR
The OTPW package, which includes the otpw-gen progam, has been developed by Markus Kuhn. The most recent version is available from
<http://www.cl.cam.ac.uk/~mgk25/otpw.html>.
