Ángel, I love the idea of making the corporate credit unions, 
payroll service, and the others that we need to use change the 
way they do things to make them more secure. However, our David 
$10 million size is not big enough to make the $2-5 billion 
Goliaths obey our wishes. We've tried and failed.

You are quite correct that "no administrative action allowed" is 
very problematic. What ability we do have is to lock that user 
name and password so it can not be used. With some providers we 
then have to go through a long process to create a new user name 
access because they delete the old one. This can be a real pain 
because we have to lock access whenever someone leaves for a 
while, pregnancy, illness lengths. In one situation we can get 
the data copied over to a new access point with the username and 
password under the control of the manager/assistant manager but 
then moving it back to the worker when they return costs again.

We do not have a system that can handle the finances the way we 
are required by law to do. We are not rich enough to pay for the 
required system as our net "profit" per year is typically less 
than $65 k per year. Our total reserve assets is just over $1 
million and that is needed to cover bad loans that happen when 
the job market crashes.

Best Wishes,
