I have two applications that require a login on my website. One of them is a Gallery application for photos and the other is a Wordpress journal. For both my username is Admin.
Norton Identity Safe doesn't just WARN me that I'm using the same username. It STOPS me from creating a second login.
Both applications have different url's and different passwords. I set each one up quite distinctly. So I either have two different names or a single name and password. The second option is a clear reduction in security. Both these applications have associated databases that require an Admin login which, whilst it CAN be changed, really makes little sense.
I've been a Norton customer for many years. Because of this, a few other Norton 360 gripes and the shambles that is NU16 then it'll be the last.
