Link should be associated with the client's social security, full stop.  Social security is a constant and will tie to the tax return, so link could actually be used.  We should also be able to delete old client accounts who have passed or are no longer clients and "Link" should change their name to something that isn't annoying to try and search for, when googling for answers.  The list is long but attaching the link account to social and deleting clients would be amazing.  And yes, I have already sent these items to Inutit.
