Yes. It should be fairly simple to generate a program that generates all strings of length 20 that will be accepted by Wells Fargo's login page. I would consider such a program a compressed version of a string containing my username and password. If you want to generate a shorter output, you might try the De Bruijn sequence.
edit: I should warn you, though, Wells is likely bankrupt, along with FDIC. If you want to plunder my accounts, you should get to work before accounting fraud becomes illegal in this country.
How about I take the easy way out and buy the integer that the Russian Mafia contracted the malware authors to steal from your less technically-inclined family members? They're just integers; who cares how I got them? You violate contracts, I buy them fifth-hand from people who don't track where they came from. 1452373618202299713253502665406299980733506930, right?
