I have an Apple ID and password which works on any browser. The same ID and Password works for Icloud which I can access on my laptop or IPhone browsers. However there is a problem, which only allows me to access Icloud through my browser. On my phone, when I navigate to 'Setting's-'Icloud'- , the Icloud ID shown is NOT the ID which works on the browser. It is an an older redundant email address. When I try to replace this old ID with the one that works on the browsers I am also stuck.: I navigate in settings from ''Sign Out- 'Delete Icloud account'' and am asked for the Password to the redundant ID address. But DO NOT t have this password. So I cannot Sign In and Delete the Account I want to replace.
