Redirect Failed Login
This little plugin allows you to manage failed login attempts. The latest version can deter hackers by adding a programmable time delay after a failed login attempt. Upon a failed login attempt, you can redirect to a page in your Joomla site, redirect to a completely different site, or not redirect at all (default). Optionally, you can have it display a custom message such as "Login Failed - please try again".
