I have run into a few problems with wordfence recently.
Today when I tried to log into my site it immediately took me to a locked out page, and did not go through the normal stage of stating that a code would be sent by text.
When I use the "If you are a site administrator and have been accidentally locked out, please enter your email in the box below and click "Send"" option, and enter my email address, the emails do not arrive until around 15 hours later, and just to rub it in they state the time they were activated (which was 15 or so hours earlier) and go on to say they have to be acted upon within 30 minutes!!
Yes, I realise I can remove wordfence from my site to gain access and then reinstall it, but I do not expect to have to go through that process so frequently, and expect this to work better.
