Hate things that don't allow you to use previous passwords as that means they are keeping a record of them. Which means when they are hacked they have a bunch of possible passwords that you could still have in use on other sites and services.
How'd you figure that? This might be a geek forum where people use hashes and unique passwords for every single website but like 99% of the rest of the population I can't remember different passwords to 100 different sites, access said sites on numerous computers and devices and think my 20-digit random assortment of letters and passwords is as strong as a 6 digit one with an exclamation mark at the end.
This,
and I think it requires some irritating combination of letters and numbers, but then makes it too short to use my existing password, so I'm stuck trying to think of something memorable but only 6-10 characters in length
Sweet jebus, what kind on ****stain programmer thought it was a good idea to limit the size of a password, save a whole byte did we?
Please die by rectal explosion.
Use your own card instead of someone else's?
I hate it mainly because I always forget the password and it prevents you from changing it to anything you've had in the past.

Doesn't bother me, the Mastercard one works in much the same way.
