[sf-lug] what's the mechanism that a website can use to prevent stored information from filling out a form?

[Michael Shiloh]

it's handy for instance when a website remembers my address or phone 
number, but it's a security risk when it remembers my account number and 
password.

what's the name of the mechanism that a website designer can use to make 
certain fields not allow stored values?

i don't need to implement this, i need to write a letter to my bank 
complaining that they allow this, and i want to use the right terms.

thanks
