So which code do we use? I downloaded the plugin, installed it, works fine. I logged out, tried to log back in, but your instructions doesn't say which of the 64 codes to use. Do we just pick one of the 64? That doesn't seem right because then a hacker now has 64 possibilities to choose from. Either way, it's another layer of protection, which is great, but I need to know which one do we choose. The automated email didn't say, just sent me the card.
Also, some advice, after I installed it, I looked all over, especially under "settings," in the admin menu and found nowhere to set any settings on this plugin. I see when I go to my user, under admin, where the link is to generate another card, but that's it. You might want to include this in your installation instructions so a webmaster/admin doesn't waste time trying to see where the settings page is for this plugin, apparently there is no settings page and nothing is created under the user's admin panel menu.
Thanks for another security product, if it works well, I'll look at your pro version when it comes out. Thanks, rg.
