Simple but effective.. this extension does what it's supposed to.
Well done to the creator, thank you for an added sense of security.

Very good extension. I found it hard to find a component that would warn me when a failed logon attempt takes place, and now I have!
Thanks for making this possible.
One thought though: the {site} parameter in the e-mail always tells you that the logon attempt was on the BackEnd,even if it was on the FronEnd.

Really good idea, very clean programmed, and easy to install and operate. It does what it says. It would be helpful if there would be the possibility to enter existing users into a whitelist. Otherwise the webmaster could easily guess passwords if they would incorrectly entered by a legitimate user.

Simpel to install and very simpel in use. Excellent to know when something wrong is happening. Looking forward to the update, where the suggestion from Londonman is put in.

Keep up the good work!

... works only, if someone missed login. If 'bad men' logs in with proper credentials, in my installation nothings happens. But e-mail alerter when user log in would be very useful.
