## Syntax {#syntax}

The [`mc anonymous set`](#command-mc.anonymous.set) command sets anonymous (i.e. unauthenticated or public) access [policies](/administration/identity-access-management/policy-based-access-control/#minio-policy) for a bucket.

Buckets with anonymous policies allow clients to access the bucket contents and perform actions consistent with the specified policy without [authentication](/administration/identity-access-management/#minio-authentication-and-identity-management).

To set anonymous bucket policies using an IAM [JSON policy](https://docs.aws.amazon.com/AmazonS3/latest/userguide/access-policy-language-overview.html), use the [`mc anonymous set-json`](/reference/minio-mc/mc-anonymous-set-json/#command-mc.anonymous.set-json) command.

**EXAMPLE**

The following command sets anonymous access policies for several buckets on the `myminio` MinIO deployment:

```shell
mc anonymous set upload myminio/uploads
mc anonymous set download myminio/downloads
mc anonymous set public myminio/public
```

Applications can perform the following operations without authentication:

- `PUT` objects to `myminio/uploads` and `myminio/public`.
- `GET` objects from `myminio/downloads` and `myminio/public`.

**SYNTAX**

The command has the following syntax:

```shell
mc [GLOBALFLAGS] policy set PERMISSION ALIAS
```

- Brackets `[]` indicate optional parameters.
- Parameters sharing a line are mutually dependent.
- Parameters separated using the pipe `|` operator are mutually exclusive.

Copy the example to a text editor and modify as-needed before running the command in the terminal/shell.

### Parameters {#parameters}

##### `PERMISSION` {#mc.anonymous.set.PERMISSION}

*mc-cmd*

*Required* Name of the policy to assign to the specified `ALIAS`. Specify one of the following values:

- `none` - Disable anonymous access to the `ALIAS`.
- `download` - Enable download-only access to the `ALIAS`.
- `upload` - Enable upload-only access to the `ALIAS`.
- `public` - Enable download and upload access to the `ALIAS`.

##### `ALIAS` {#mc.anonymous.set.ALIAS}

*mc-cmd*

*Required* The full path to the bucket or bucket prefix to which the command applies the specified [`PERMISSION`](#mc.anonymous.set.PERMISSION).

Specify the [alias](/reference/minio-mc/mc-alias-set/#alias) of the MinIO or other S3-compatible service *and* the full path to the bucket or bucket prefix. For example:

```shell
mc anonymous set public play/mybucket
```

Specify a bucket prefix to set the policy on only that prefix. For example, this command sets distinct anonymous bucket policies on the `mybucket/downloads` and `mybucket/uploads` prefixes:

```shell
mc anonymous set download play/mybucket/downloads
mc anonymous set upload play/mybucket/uploads
```

### Global Flags {#global-flags}

This command supports any of the [global flags](/reference/minio-mc/#minio-mc-global-options).

## Examples {#examples}

### Set Anonymous Policy for Bucket {#set-anonymous-policy-for-bucket}

Use [`mc anonymous set`](#command-mc.anonymous.set) to set the anonymous policy for a bucket:

```shell
mc anonymous set POLICY ALIAS/PATH
```

- Replace [`POLICY`](#mc.anonymous.set.PERMISSION) with a supported [`permission`](#mc.anonymous.set.PERMISSION).
- Replace [`ALIAS`](#mc.anonymous.set.ALIAS) with the [`alias`](/reference/minio-mc/mc-alias/#command-mc.alias) of a configured S3-compatible host.
- Replace [`PATH`](#mc.anonymous.set.ALIAS) with the destination bucket.

## Behavior {#behavior}

### S3 Compatibility {#s3-compatibility}

SILO is the supported server for PGSTY mcli; compatibility with upstream MinIO and other S3 services is [best effort](/reference/minio-mc/#command-mc).
