Login LockDown records the IP address and timestamp of every failed login attempt. If more than a certain number of attempts are detected within a short period of time from the same IP range, then the login function is disabled for all requests from that IP address. This helps to prevent brute force password discovery and attacks.
The plugin defaults to a 1 hour lock out of an IP block after 3 failed login attempts within 5 minutes. This can be modified in options. Administrators can release locked out IP ranges manually from the panel.
Configure the plugin from Settings – Login LockDown
- Extract the zip file into your plugins directory into its own folder.
- Activate the plugin in the Plugin options.
- Customize the settings from Settings – Login LockDown panel.
