Is there any way to change the sysdba password when releasing an application
to someone?

I have a Delphi application that uses a Firebird database (was using 1.5 but
will now use 2.1).

Is there any way to change the password so people cannot directly access the
database? At the moment I have the password hardcoded into the Delphi
application.

I would prefer to protect the database which a unique password that I could
hardcode into my application (or at least put the password in the registry
or somewhere) but is this possible?

Thanks,
Stephen
