## 返回 Token { #return-the-token }

`token` 端点的响应必须是 JSON 对象。

响应返回的内容应该包含 `token_type`。本例中用的是**Bearer**Token，因此， Token 类型应为**`bearer`**。

返回内容还应包含 `access_token` 字段，它是包含权限 Token 的字符串。

本例只是简单的演示，返回的 Token 就是 `username`，但这种方式极不安全。

/// tip | 提示

下一章介绍使用哈希密码和 <abbr title="JSON Web Tokens - JSON Web 令牌">JWT</abbr> Token 的真正安全机制。

但现在，仅关注所需的特定细节。

`AssumeRoleWithCustomToken` STS API extension. A user or application can now present a token to the `AssumeRoleWithCustomToken` API, and MinIO verifies this token by sending it to the Identity Management Plugin webhook. This plugin responds with some information and MinIO is able to generate temporary STS credentials to interact with object storage.

The authentication flow is similar to that of OpenID, however the token is "opaque" to MinIO - it is simply sent to the plugin for verification. CAVEAT:...
