Sometimes, we get the flood of Unlimited attempts of login fail message, block user, block IP. In that case our website handle unwanted extra data, extra burden on database that is not good for our website health.
So what we have to do, in Drupal 7, we have module that name is "Flood control" https://www.drupal.org/project/flood_control
But in Drupal 8 we don't have that module, So many times we get the error message that is very famous: "Login blocked after 5 failed login attempts".
In that case or if we want to overcome this problem Drupal 8 we have solution, we are going to share:
Code for Flood limit change:
$flood_limit = 5; //Default value is 5, change whatever you want.
// for login form
\Drupal::configFactory()->getEditable('login.settings')
->set('flood.limit', $flood_limit)
->save();
// for contact form
$flood_limit = 5; //Default value is 5, change whatever you want.
\Drupal::configFactory()->getEditable('contact.settings')
->set('flood.limit', $flood_limit)
->save();
Code for Flood interval change:
// for login form
$flood_interval = 3600; //Default value is 3600sec (1hour), change whatever you want
\Drupal::configFactory()->getEditable('login.settings')
->set('flood.interval', $flood_interval)
->save();
// for contact form
$flood_interval = 3600; //Default value is 3600sec (1hour), change whatever you want
\Drupal::configFactory()->getEditable('contact.settings')
->set('flood.interval', $flood_interval)
->save();
Important Notice: Put this code in custom module or template or theme file.
Or we can use 'settings.php' option for this code
$flood_limit = 10;
$config['login.settings']['flood']['limit'] = $flood_limit;
And another we have a module in drupal 8, we can use this and all this code feature is there. Please find this "Flood settings" module. https://www.drupal.org/project/flood_settings
