I believe he means that the user has a 10 digits pin and the form asks
for some randomly selected digits.

I.E: the pin is 0192837465
if the form asks for 1234 the user will have to enter 0192
if the form asks for 5678 the user will have to enter 8374
if the form asks for 1357 the user will have to enter 0987
Etc.

I came across some eBanking and Mobile Banking (via SMS) applications
using this system in Indonesia.

Paolo

Is the 1st pin ('1234') static?  I.e., does it change into '0192',
requiring the user to write down their current PIN after every login?
I'm guessing that's not the case b/c of the difficulties users would
have with such a system.

So, assuming '1234' is your PIN all the time, and the temporary '0192'
changes each login, you're effectively using '1234' as the password
every time.  The '0192' is irrelevant from a security perspective, and
probably an unneeded burden on your users.  It doesn't buy you any
more security that I can see, other than requiring two passwords
('1234' and 'password').  It is not two-factor or a similar solution.

has any ever tested a https portal?


basically i have a client who has constructed a https portal to all
works logon on from anywhere and access apps and files.


how it works is the username and pw are the users AD logon details,
the pin is emailed to the user, so for example when the user logs on
he has a button saying generate pin!


now say for example he has a pin of 1234 when hits generate pin a
picture comes up like this


1234567890

0192837465


so the user find his 1st number in his pin, and types the number below
it, same with 234 and enters that into the pin field:


username: bloggs

pw: password

pin: 0192


the pin is one time unique! has anyone ever come across a setup like
this?


sorry for the long post!


hope you can help!
