# Removing authorization from a datashare in Amazon Redshift
Removing authorization from a datashare

With Amazon Redshift, you can control access to datashares by revoking authorization for specified consumers. This sections provides instructions for revoking consumer access to your datashares in Amazon Redshift.

**Note**  
To remove authorization for the datashare, there must be at least one data consumer added to the datashare.

------
#### [ Console ]

Choose one or more consumer clusters that you want to remove authorization from. Then, choose **Remove authorization**.

After authorization is removed, data consumers lose access to the datashare immediately.

------
#### [ API ]

The producer security administrator determines the following:
+ Whether or not another account can have access to the datashare.
+ If an account has access to the datashare, whether or not that account has write permissions.

The following IAM permissions are required to deauthorize a datashare: 

**redshift:DeauthorizeDataShare**

You can deauthorize usage and writes using either a CLI call or with the API:

```
deauthorize-data-share
--data-share-arn <value>
--consumer-identifier <value>
```

For more information about the command, see [deauthorize-data-share](https://docs.aws.amazon.com/cli/latest/reference/redshift/deauthorize-data-share.html).
