I would suggest the installation of a security plugin such as Wordfence to protect against such hacking attempts
The added protection is fine – it’s just that the message for Dave made me think that I’d been hacked. Something a little less frightening perhaps signed by Eli!
I have had the same problem and have to say that the message frightened the life out of me until I googled the phrase. Can you put a less innocuous message in? The problem occurred for me when I tried to use the Android app for managing multiple WP sites.
