Configure sybase control center to accept multiple device ID?

In my HWC application, I want to keep single user name and password for all the users.Also, when/each time application will be opened by any user it should not ask user name and password again and again.

I'm thinking to implement it in following ways, please help me to find out which will be quicker to implement.

1. Configure sybase control center to accept multiple device ID.But do not know if it is possible or not.If possible, then How?

2. Get the HWC code from "C:\Sybase\UnwiredPlatform\MobileSDK213\HybridWeb " and modify the "sybase settings" code (add two more field "username" and "password"). Map the SCC registered "user" with the "username" and "password" field.

3. Keep a SQlite/Ultralite database to save username and password when 1st time user login and read after words.

Plaese let me know, if there is any other quicker way to do this. Or I can use any of above mentioned points ??

Thanks.
