I'm trying to authorize my computer to use with a particular vendor. I've chosen the Vendor (NYPL). I've typed in my Vendor user name and password -- I assume those terms refer to the user ID and password that I use to access the Vendor. It's rejected over and over, saying ID or password aren't correct (They are correct). Am I assuming correctly?
Also, if I opt now not to authorize the computer, can I change that later?
