Have you tried clicking on Sign-in options and choosing password and entering your password?
If you still want to use the PIN type the first three numbers and click on the little ‘eye’ icon at the end of the box that you enter the PIN in this will show you what you have already typed. Check it is OK before you enter the last digit.
Hope that help.
