Web AppBuilder for Arcgis: how to cache username and password

[HabG_]

Hi All,

I have a Web AppBuilder site that uses a secure service which is accessed with a username and password. The ArcGIS Server configuration setting are as shown in the image below:

Every time I access the web mapping application or every time I refresh my browser, I get the Sign In box. Can anyone tell me how to configure the application so that the user can only sign in and his/her credential can be cached for the whole day?

Thanks

Hab
