I have an MBO which invokes a web service. I need to be able
to define the web service credentials on the device. I
initially used the credential request starting point on the
form, but it appears this presumed the logon details I enter
are SUP credentials.

I have therefore assigned the personalization key 'user_pk'
to the MBO authentication.

When I run the workflow from a device, I get the error 'The
security context does not contain the parameter key

Do I need to do something else with this personalization key
in order for this security issue to be resolved.

I do not know if this is the correct way to get the
credential details from the device and would appreciate any
