Manage your Apple ID
Given your Apple ID gives full access to your Apple services, it’s crucial it’s secured with a strong password — one you can store in your password manager. Tap Settings (iOS), open System Prefs (macOS), or log into appleid.apple.com in a browser, then tap your Apple ID followed byPassword & Security. You’ll see when it was last changed — consider doing so every 12 months or so.
