FAQ
-
Where are the configuration settings?
-
There are none. If the plugin is active, then it is banning all of its known weak passwords.
-
What if one of my users is already using one of those passwords?
-
If they try to log in with one of these weak passwords, then they will not succeed, and they will be told to use the ‘Lost Password’ procedure to obtain a new password.
-
What passwords does this plugin ban?
-
The 3546 listed in the “common passwords list” as obtained from https://www.openwall.com/passwords/wordlists/ on 16th November 2012.
-
I’d like to change the policy; add some different words; forbid too-short passwords, etc.
-
Please either send a patch, or make a donation on my donation page, and I will be glad to help. Otherwise, this plugin does all I wanted it to do and I’ve not got time to develop it further without some compensation.
