En este ejemplo usamos headers personalizados inventados `X-Key` y `X-Token`.

Pero en casos reales, al implementar seguridad, obtendrías más beneficios usando las [Utilidades de Seguridad integradas (el próximo capítulo)](../security/index.md){.internal-link target=_blank}.

* `breaking`: Breaking Changes
    * Existing code will break if they update the version without changing their code. This rarely happens, so this label is not frequently used.
* `security`: Security Fixes
    * This is for security fixes, like vulnerabilities. It would almost never be used.
* `feature`: Features
    * New features, adding support for things that didn't exist before.
* `bug`: Fixes

minio server /mnt/data
```

Assuming that MinIO server is configured to support STS API by following the doc [MinIO STS Quickstart Guide](https://docs.min.io/community/minio-object-store/developers/security-token-service.html), execute the following command to temporary credentials from MinIO server.

```
go run client-grants.go -cid PoEgXP6uVO45IsENRngDXj5Au5Ya -csec eKsw6z8CtOJVBtrOWvhRWL4TUCga

Mas em situações reais, como implementações de segurança, você pode obter mais vantagens em usar as [Ferramentas de segurança integradas (o próximo capítulo)](../security/index.md){.internal-link target=_blank}.
