Q: How do I recover or change icloud email password. I've forgotten mine

Go to http://iforgot.apple.com and sign in with your iCloud login. A new password will be sent to your associated email address.

If this doesn't work you will need to contact Support. Go to https://getsupport.apple.com; click' See all products and services', then 'More Products and Services, then 'Apple ID', then 'Other Apple ID Topics' then 'Lost or forgotten Apple ID password'.
