# Authentication

In the Open Source version of YDB, working with topics via the Amazon SQS protocol is supported only without authentication.

## Cluster setup

To disable authentication, in the `security_config` section of the [cluster configuration file](https://ydb-platform--ydb.viewer.diplodoc.com/en/reference/configuration/security_config.md#security-auth), set the `enforce_user_token_requirement` parameter to `false`:


```yaml
security_config:
  enforce_user_token_requirement: false
```
