-Brute Force Protection
-======================
-
-The brute force protection of Kanboard works at the user account level:
-
-- After 3 authentication failure for the same username, the login form shows a captcha image to prevent automated bot tentatives.
-- After 6 authentication failure, the user account is locked down for a period of 15 minutes.
-
-This feature works only for authentication methods that use the login form.
-
-However, **after three authentication failure through the user API**, the account has to be unlocked by using the login form.
-
-Kanboard doesn't block any IP addresses since bots can use several anonymous proxies. However, you can use external tools like [fail2ban](http://www.fail2ban.org) to avoid massive scans.
-
-Configuration
--------------
-
-Default settings can be changed with these configuration variables:
-
-```php
-// Enable captcha after 3 authentication failure
-define('BRUTEFORCE_CAPTCHA', 3);
-
-// Lock the account after 6 authentication failure
-define('BRUTEFORCE_LOCKDOWN', 6);
-
-// Lock account duration in minutes
-define('BRUTEFORCE_LOCKDOWN_DURATION', 15);
-```
-
-Unlocking users
----------------
-
-If you don't want to wait 15 minutes, you can unlock a user from the user interface.
-As administrator, go to the user profile and click on "Unlock this user".
