Can I change the Security Que & Ans text?

Can I change the Security Que & Ans text?

When enrolling the text above the security questions says
 
"Length Specification
  • The minimum length of the answer(s) should be 5 characters and maximum allowed is 255 characters"
Can I amend this?
 
I would like to to say give the answer length and also to advise people that they can us pass phrases, if I can do this then I can change the questions to make them better than the standard "mother's maiden" name and other things that people can find on social networking sites!
 
Thanks
