Features: Max retries: You have the power to choose how many attempts a user can make before the user is blocked; Lockdown: This prevents the user from being able to use the login form after too many retries; Email notifications: We’ll report a user lockdown to you via email; Hide lost password: Hides the “Forgot your password?” link from the login form page. This plugin does not make any changes to core: When you delete/uninstall the plugin, everything will revert back to normal.
