摘自Yodlee的put providerAccount API文档here
它说我必须传递loginForm数据以及用户的凭证：
5. If the credentials have to be updated in the Yodlee system, one of the following should be provided as input to this service:
a. LoginForm
b. Field array
6. The loginForm or the field array are the objects under the provider object that is obtained from the get provider details service response.
7. The credentials provided by the user should be embedded in the loginForm or field array object.
问题
这是否意味着我应该保存或以某种方式存储了用户的银行凭据？
当我浏览Fastlink上的刷新流程时，它会以某种方式预先填充凭据，而我所要做的就是单击“继续”； Fastlink如何做到这一点？如果Fastlink可以做到这一点，我的猜测是有一种编程方式可以做到这一点
