Bernd what your saying is disturbing.
First, it completely contradicts what IINET rep wrote here
about needing to enter the full password for verification and not having
access to plain text at all. so what you did with the rep on the phone is
not suppose to be possible.
Second, users shouldn't give their passwords to anyone not even part of it.
There were enough scams by people calling customers claiming they are
company rep and asking the passwords of users. we don't need legitimate
customer reps doing the same.
We can achieve much more better solution with single use tokens like Google
Auth if you really want to take it to the next level.
But never do it with users passwords since you open yourself to a new
vector of attack.

I'm buying the rest of IINET claims which are very noob level and I'm not
their customer so I don't really care, but it seems like their doing
something horribly wrong.

* And just for a jibs I don't  keep my passwords under a silo under
mountain in fact here is one of my password stored hash that I already
published to an online forum 3 months ago -


If this is not secure you are welcome to publish this password here in the
clear once you get it
