# POST /#X-Amz-Target=TrentService.DeleteAlias

`POST /#X-Amz-Target=TrentService.DeleteAlias`

Deletes the specified alias.

Adding, deleting, or updating an alias can allow or deny permission to the KMS key. For details, see [ABAC for KMS](https://docs.aws.amazon.com/kms/latest/developerguide/abac.html) in the _Key Management Service Developer Guide_.

Because an alias is not a property of a KMS key, you can delete and change the aliases of a KMS key without affecting the KMS key. Also, aliases do not appear in the response from the DescribeKey operation. To get the aliases of all KMS keys, use the ListAliases operation.

Each KMS key can have multiple aliases. To change the alias of a KMS key, use DeleteAlias to delete the current alias and CreateAlias to create a new alias. To associate an existing alias with a different KMS key, call UpdateAlias.

**Cross-account use**: No. You cannot perform this operation on an alias in a different Amazon Web Services account.

**Required permissions**

*   [kms:DeleteAlias](https://docs.aws.amazon.com/kms/latest/developerguide/kms-api-permissions-reference.html) on the alias (IAM policy).
    
*   [kms:DeleteAlias](https://docs.aws.amazon.com/kms/latest/developerguide/kms-api-permissions-reference.html) on the KMS key (key policy).
    

For details, see [Controlling access to aliases](https://docs.aws.amazon.com/kms/latest/developerguide/kms-alias.html#alias-access) in the _Key Management Service Developer Guide_.
