as usual, a repeat loop with "for each" will be incredibly faster.

Just in case the userbase will grow you could script:
(Presumed that the lines are in this format: username TAB coded password)

...
set the itemdel to TAB
repeat for each line l in myFile
    if item 1 of l is the_user then
     put item 2 of l into the_password
     exit repeat
   end if
ask "Please enter more money ehmm your password"
if it is the_password then
   do_the_right_thing
end if
...

"for each" can process up to thousands of lines in a fraction of a 
second !
No foolin' ;-)

Hope that helps...
