# Login Attempts Properties

As of KCM version 2.9.6, KCM can be configured to limit a user's ability to login after multiple consecutive failed login attempts. This blocks brute-force login attacks on KCM instances.

{% hint style="info" %}
By default KCM will lock a user out of logging in for 5 minutes after 5 failed attempts
{% endhint %}

Use the following properties to change the login attempt settings

| Property                   | Description                                                                                        |
| -------------------------- | -------------------------------------------------------------------------------------------------- |
| `ban-max-invalid-attempts` | The number of invalid attempts before a user is locked out                                         |
| `ban-address-duration`     | The amount of time in seconds a user is locked out for after hitting the invalid attempts limit    |
| `ban-max-addresses`        | The number of addresses that KCM will track to check for invalid attempts.  Defaults to `10485760` |
