My company has been distributing an (external) software package for 30 years.  In the 
standard distributive, there are 3 users defined with 3 standard passwords, to use for the

initial demo and user training.  The documentation has a prominent section in capitals and

red color that says that the passwords of these users should be changed, or these users 
deleted as soon as the initial testing phase is over.
When I go visit customers however, about 50% of them still have these users enabled with 
the original passwords, even at some very security-conscious places.

Users are like that.

So yes, by any means, have the Manager disabled by default, even when subsequently enabled

restrict it by default to localhost, and in the documentation and examples, use some 
password that is guaranteed NOT to work and MUST be changed. "******" may be a good way to

suggest that it has to be changed, though I am sure that there will be users trying it
