iCloud reset password?
I forgot my password on icloud. How do I reset my password?
Reset it here: https://iforgot.apple.com/iForgot/iForgot.html. Once you have your new password, to change it for iCloud on your phone you'll have to go to Settings>iCloud, scroll to the bottom and tap Delete Account. This will delete the account and synced data from your phone but not from iCloud. Then sign back in with your new password and turn your iCloud data syncing back to On, and when prompted, choose Merge.
