You can provide a custom certs directory using `--certs-dir` command line option.

#### Credentials

On MinIO admin credentials or root credentials are only allowed to be changed using ENVs namely `MINIO_ROOT_USER` and `MINIO_ROOT_PASSWORD`.

```sh
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio13
minio server /data
```

	if errCode != ErrNone {
		return cred, "", "", time.Time{}, errCode
	}

	cred, _, errCode = checkKeyValid(r, signV4Values.Credential.accessKey)
	if errCode != ErrNone {
		return cred, "", "", time.Time{}, errCode
	}

	// Verify if region is valid.
	region = signV4Values.Credential.scope.region

	// Extract date, if not present throw error.
	var dateStr string

}
```

These credentials can now be used to perform MinIO API operations, these credentials automatically expire in 1hr. To understand more about credential expiry duration and client grants STS API read further [here](https://github.com/minio/minio/blob/master/docs/sts/client-grants.md).
