# TOTP

The TOTP node provides a way to generate a TOTP (time-based one-time password).

{% hint style="info" %}
**Credentials**

Refer to [TOTP credentials](/integrations/builtin/credentials/totp.md) for guidance on setting up authentication.
{% endhint %}

## Node parameters <a href="#node-parameters" id="node-parameters"></a>

{% hint style="info" %}
**This node can be used as an AI tool**

This node can be used to enhance the capabilities of an AI agent. When used in this way, many parameters can be set automatically, or with information directed by AI - find out more in the [AI tool parameters documentation](/build/integrate-ai/ai-examples/use-ai-for-parameters.md).
{% endhint %}

Configure this node with these parameters.

### Credential to connect with <a href="#credential-to-connect-with" id="credential-to-connect-with"></a>
