Hi Ali
No problem and thanks for the response.
Meanwhile, I've managed to install the plugin.
(Just a small oversight on my part, which made that it didn't worked at first.)
Now it works perfectly on 4.1.12
I've noticed this too.
If I, lets say, enter 7 times in succession a wrong password for the Admin,
then I receive 7 messages in my mailbox.
So far so good.
But, when I look at the _strikes table in my database, I see no record of this event,
which means that the waiting time of 15 minutes after 5 incorrect login attempts is circumvented.
When a cracker tries to break in with password-cracking software,
the mailbox will be flooded with messages.
Because there is no restriction on the number of login attempts, the cracker can continue to enter passwords without delay.
Maybe you can implement something, with which the 5 times (failed) login limit is preserved.
Otherwise, a great plugin

Good work :up:
