credit freeze

Hi Terry, I have my wifes’ and my credit reporting agency accounts frozen and have had for years. We don’t need to open loans to pay for things. Since it’s only a matter of time before the next credit agency is hacked like Equifax was recently, I think it would be wise to freeze my 19YO sons 3 credit reporting agencies. He likely will need to open loans as he gets into his 20’s and will need some decent credit ratings. Look forward to your thoughts.
Thanks
