| RoleArn         | String  | Yes      | Must match the Role ARN generated for the identity plugin            |
| DurationSeconds | Integer | No       | Duration of validity of generated credentials. Must be at least 900. |

The validity duration of the generated STS credentials is the minimum of the `DurationSeconds` parameter (if passed) and the validity duration returned by the Identity Management Plugin.

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).
