本节描述了PDS的账号管理的最佳实践，您可以参考该文档对账号进行管理。
PDS会将用户与账号绑定，用户与账号的绑定关系示意图如下：
绑定的具体方式为：
{"items":[{"authentication_type":"email","created_at":1692345217628,"display_name":"12*@aliyunpds.com","domain_id":"bj1","extra":"","identity":"12*@aliyunpds.com","user_id":"c9b7a5aa04d14ae3867fdc886fa01da4"},{"authentication_type":"mobile","created_at":1692345217822,"display_name":"139****","domain_id":"bj1","extra":"","identity":"139****","user_id":"c9b7a5aa04d14ae3867fdc886fa01da4"}]}可以看到该用户含有email和mobile的两条账号信息
请求body示例
{'identity':'139****','type':'mobile'}返回body示例
请求body示例：
{"user_id":"c9b7a5aa04d14ae3867fdc886fa01da4"}返回body示例：
{"items":[{"authentication_type":"email","created_at":1692345217628,"display_name":"12*@aliyunpds.com","domain_id":"bj1","extra":"","identity":"12*@aliyunpds.com","user_id":"c9b7a5aa04d14ae3867fdc886fa01da4"},{"authentication_type":"mobile","created_at":1692345217822,"display_name":"139****","domain_id":"bj1","extra":"","identity":"139****","user_id":"c9b7a5aa04d14ae3867fdc886fa01da4"}]}
{"identity":"139****","type":"mobile","user_id":"c9b7a5aa04d14ae3867fdc886fa01da4"}返回body示例：
{"identity":"139****","type":"mobile","user_id":"c9b7a5aa04d14ae3867fdc886fa01da4"}返回body示例：当前API无返回参数，仅返回HTTP响应状态码：204
注意：调用该接口仅删除该条账号，但不会修改用户的属性信息，即在用户的属性信息中仍然能查询到："phone":"139****"
