# Authenticate S3

### Ensure that DataSyncs has correct permissions to access your S3 bucket

We currenty support two authentication methods: 

{% content-ref url="authenticate-s3/use-an-s3-user" %}
[use-an-s3-user](https://docs.hockeystack.com/datasyncs/connecting-your-warehouse/authenticate-s3/use-an-s3-user)
{% endcontent-ref %}

{% content-ref url="authenticate-s3/use-an-iam-role" %}
[use-an-iam-role](https://docs.hockeystack.com/datasyncs/connecting-your-warehouse/authenticate-s3/use-an-iam-role)
{% endcontent-ref %}

After creating the necessary permissions, you can configure this within the configuration screen in HockeyStack. <br>
