How should I go about convincing them that Amazon.com is wrong and the fact that they haven't had a severe account breach is no reason not to implement a policy ourselves? Or, to play devil's advocate with myself, if I'm wrong, why doesn't Amazon enforce a password policy?
as usual, you have to compare the cost of the change to the benefits. The cost is that more complicated password procedures *will* drive some users (potential customers) away. The benefit is that fewer user accounts will be hacked. So how big is the damage that can be done through a hacked user account, and how likely is it that a hacker will actually create that much damage? IMO, for Amazon the potential damage is medium (the attacker can order lots of stuff for someone else), and the likelihood is low (because the attacker can't draw a profit from the attack). OTOH, 1% fewer customers due to "complicated" password requirements would be a big loss to Amazon. So while Amazon's reasoning may be perfectly valid, it's not necessarily valid for you. It depends on your situation. (Apart from that, I wouldn't vote for password expiry, especially not in a web application. How do you deal with expired accounts? Delete them? Notify users before expiry? Whatever you do, it adds to the "cost" side of the argument.)
