I have also had this same problem since updating my phone.. I was going to try your advice when I couldn't press 'use secure credentials' because it was asking for a password, I didn't set one, nor can I guess what it may be...
By mistake I have pressed the 'clear all credentials' and now I am unable to press 'use secure credentials' Is there any way of undoing this?
P.S. Sorry if that sounds very confusing!
