Alternatively, you can create an Apple ID through the App Store by signing out of iCloud, opening the App Store app, tapping the avatar icon, and selecting "Create New Apple ID." Follow the onscreen instructions including entering email, password, billing info (or select None), and verification. You can also create an Apple ID on other devices like Mac or Windows PC via system settings or Apple Music/TV apps, or on the web at Apple's website. After creation, verify your email via the confirmation link Apple sends you. Your Apple ID allows access to Apple services like iCloud, App Store, etc.
