How does it work over the phone...
When I phone my bank, as part of the validation process they ask me to correctly state certain key characters of my password...
Bank : What is letter two of your password?
Me : Err.. it's kind of a sad Japanese looking girl with rosy cheeks and a tear in her eye.
Bank : And letter number seven?
Me : It's a happy looking dog.
Bank : No that's incorrect.
Me : A miserable cat?
Bank : No.
Me : A happy horse?
