I did use the password on a few sites, but all but one, aside from Family Relatives, is defunct. Can't do much about that. So I guess all I can do is change the live one and hope for the best.
I have discovered that Family Relatives has, since I stopped using them about a decade ago, has gone from good, to very bad according to several rating sites. They now get about 1 star. Mostly, it is about charging more than the customer contracted for and then being unobtainable, and not refunding money.
Thanks for your help.
