# Flood Contorl

The [Flood Control](https://www.drupal.org/project/flood_control) module provides a simple interface to configure hidden flood control options and provides the ability to remove IP addresses and user IDs from the flood table.

The **Flood Control** module is installed and enabled in Varbase by default, site admins are given access to the Flood Unblock table where the list of blocked IP addresses and user IDs can be seen.

### Unblocking Blocked Users and IPs

The **Flood Unblock** table can be accessed by navigating to **Administration** \ **People \\** _**Flood Unblock**_.

The table shows the blocked users with other information like the timestamp of the failed login.
