webapp creator app / webapp-generator script option to safe login data

[Bastos]

Hy together,

I want to build a webapp with webapp-creator or similar tools for the carsharing service flinkster.

Therefor I need to login and I want the webapp to remember my login info.

Is there a way to say the webabb creator app or the webapp-generator script to safe the login data in the container?

Or is there another easy way to create a webapp with this feature ?
