# 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](https://help.aristotlemetadata.com/administrator-tasks/contact-forms).
### How to adjust spam detection options
1. Select 'Aristotle Cloud Dashboard' from the dashboard side panel.
2. Select 'View registry settings'.
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.
