Thank you so much for all this Johanna....the problem was that once I'd turned off keychain! it wouldn't let me go back in as it needed verification, which was then sent by SMS. Of course it was being sent to the wrong number!....I had to go through Apple Support who sorted it by overriding the SMS bit, which then allowed me to turn on Keychain, giving me the option to edit - that hadn't been there previously. It was a catch 22 situation. Hope that all makes sense! Johanna - I have to tell you, Apple Support struggled with telling me how to edit and I told them using your directions! What a star you are! Anyway it's done now....thank you once again.
