# auth

Available in Classic and VPC

Output the environment variables used for authentication in a format that can be used directly in the shell.

## Syntax

The `auth` syntax is as follows:

```
swift auth
```

## Options

`auth` does not support sub-options; values required for authentication must be specified as common options. For information about the options common to all `swift` subcommands, see [Archive Storage options](/docs/en/guide-archivestorage#%EC%98%B5%EC%85%98).

## Examples

If the authentication request is successful, the `export` command will be displayed, setting the storage URL and authentication token as environment variables.

### Command

The command example is as follows:

```
swift --os-auth-url https://kr.archive.ncloudstorage.com:5000/v3 --auth-version 3 \
    --os-username {access_key_id} --os-password {secret_key} \
    --os-user-domain-id {domain_id} --os-project-id {project_id} \
    auth
```

### Output

The output example is as follows:

```
export OS_STORAGE_URL=https://kr.archive.ncloudstorage.com/v1/AUTH_a1b2c3d4e5f64a7b8c9d0e1f2a3b4c5d
export OS_AUTH_TOKEN=<token-redacted>
```

Once you run the `export` command that was displayed, you can use `OS_STORAGE_URL` and `OS_AUTH_TOKEN` in subsequent requests without having to re-authenticate.
