# RabbitMQ credentials

You can use these credentials to authenticate the following nodes:

* [RabbitMQ](/integrations/builtin/app-nodes/n8n-nodes-base.rabbitmq.md)
* [RabbitMQ Trigger](/integrations/builtin/trigger-nodes/n8n-nodes-base.rabbitmqtrigger.md)

## Supported authentication methods <a href="#supported-authentication-methods" id="supported-authentication-methods"></a>

* User connection

## Related resources <a href="#related-resources" id="related-resources"></a>

Refer to [RabbitMQ's Connections documentation](https://www.rabbitmq.com/docs/connections) for more information about the service.

## Using user connection <a href="#using-user-connection" id="using-user-connection"></a>

To configure this credential, you'll need to have a [RabbitMQ broker](https://www.rabbitmq.com/) installed and:

1. Enter the **Hostname** for the RabbitMQ broker.
2. Enter the **Port** the connection should use.
3. Enter a **User** the connection should use to log in as.
   * The default is `guest`. RabbitMQ recommends using a different user in production environments. Refer to [Access Control | The Basics](https://www.rabbitmq.com/docs/access-control#basics) for more information. If you're using the `guest` account with a non-localhost connection, refer to [`guest` user issues](#guest-user-issues) below for troubleshooting tips.
4. Enter the user's **Password**.
   * The default password for the `guest` user is `guest`.
5. Enter the [virtual host](https://www.rabbitmq.com/docs/vhosts) the connection should use as the **Vhost**. The default virtual host is `/`.
6. Select whether the connection should use **SSL**. If turned on, also set:
   * **Passwordless**: Select whether the SSL certificate connection users SASL mechanism EXTERNAL (turned off) or doesn't use a password (turned on). If turned on, you'll also need to enter:
     * The **Client Certificate**: Paste the text of the SSL client certificate to use.
     * The **Client Key**: Paste the SSL client key to use.
     * The **Passphrase**: Paste the SSL passphrase to use.
   * **CA Certificates**: Paste the text of the SSL CA certificates to use.

## guest user issues <a href="#guest-user-issues" id="guest-user-issues"></a>

If you use the `guest` user for the credential and you try to access a remote host, you may see a connection error. The RabbitMQ logs show an error like this:

```
[error] <0.918.0> PLAIN login refused: user 'guest' can only connect via localhost
```

This happens because RabbitMQ prohibits the default `guest` user from connecting from remote hosts. It can only connect over the `localhost`.

To resolve this error, you can:

* Update the `guest` user to allow it remote host access.
* Create or use a different user to connect to the remote host. The `guest` user is the only user limited by default.

Refer to ["guest" user can only connect from localhost](https://www.rabbitmq.com/docs/access-control#loopback-users) for more information.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.n8n.io/integrations/builtin/credentials/rabbitmq.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
