Fat Client Login with barcode

Thw article “WMS Mobile Client - Login using barcode" describes how to use a Login Barcode Creator to create a barcode containing username and password for user at the fat clients login screen.

But unfortunately the password is not encrypted in the barcode.

It would be great to have a function within WMS for creating a barcode with a encrypted password, and (of course) to have the decoding functionality at login screen.
