# Adjusting spam detection options

{% hint style="info" %}
Spam detection options can only be adjusted by an Administrator.
{% endhint %}

Spam detection options can be used to adjust settings that govern the use of reCAPTCHA in any created [contact forms](/administrator-tasks/contact-forms.md).

### How to adjust spam detection options

1. Select 'Aristotle Cloud Dashboard' from the dashboard side panel.

3. Under the appropriate subheading, you may adjust the following:
   * 'Spam Detection Option': Toggles between the use of user provided key pairs, or Aristotle provided key pairs:
     * 'User provided key pairs': Key pairs acquired directly from Google by the user
     * 'Aristotle provided key pairs': Key Pairs acquired from Google by Aristotle, but offered to the user for use.

**Notes:**

* A key pair is used to achieve one way, asymmetric encryption. A site key is used to encrypt content, and a secret key to decrypt it. This form of encryption is impossible with more generic methods, like passwords. See [Google](https://www.google.com/recaptcha/about/) for information and configuration.
* Spam detection statistics can be tracked internally when using user provided key pairs. The statistics of Aristotle provided key pairs can be tracked only by Aristotle.
