# 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.
