# Setting Up OpenSearch User Permissions for Username and Password Authentication

If you're using AWS OpenSearch in your Immuta installation, use this how-to to set up the proper permissions needed for username and password authentication.

1. In the AWS console, [create an OpenSearch domain](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/createupdatedomains.html#createdomains) and create a master user. This user will set up the permissions for the audit user.
2. In the OpenSearch console, [create a new user](https://opensearch.org/docs/latest/security/access-control/users-roles/#defining-users). This user will be the audit user. You will enter the username and password for this user when installing Immuta.
3. [Create a role](https://opensearch.org/docs/latest/security/access-control/users-roles/#defining-roles) for the audit user.
4. Add the audit user to the role.
5. Create the two additional roles to hold the following permission groups. Immuta recommends permission groups for a smooth configuration, but just ensure the user has all the following permissions.
   * **immuta\_cluster\_permission\_grp** with the following permissions:
     * cluster:monitor/health
     * indices:data/write/bulk
     * indices:data/write/bulk\*
     * indices:data/read/scroll
     * indices:data/read/scroll/clear
     * indices:monitor/settings/get
   * **immuta\_index\_permission\_grp** with the following permissions for the `*` index:
     * indices:admin/aliases
     * indices:admin/aliases\*
     * indices:admin/exists
     * indices:admin/create
     * indices:admin/delete
     * indices:admin/settings/update
     * indices:admin/get
     * indices:admin/refresh
     * indices:admin/refresh\*
     * indices:admin/mapping/put
     * indices:data/read/search
     * indices:data/read/scroll
     * indices:data/read/scroll/clear
     * indices:data/write/delete
     * indices:data/write/delete/byquery
     * indices:data/write/index
     * indices:data/write/bulk
     * indices:data/write/bulk\*
     * indices:monitor/settings/get
6. Add the additional roles with the permission to the audit user's role.

After these steps are complete, your audit user should have the required permissions and you can [complete the Immuta install](/latest/configuration/self-managed-deployment/install/managed-public-cloud.md) using the user's username and password.
