If you do not have a Social Security online account and think you might want it, go ahead and create the SS account before implementing the credit freeze. Otherwise, you will need to
thaw Experian to create the SS account.
A few months ago, I used the Clark Howard steps to freeze online. He was right about TransUnion being difficult. It would let me complete one section then log me out. I would log back in and complete another section just to be logged out again. I was finally able to complete all the steps. Keep the PINs!
