Disable Access to iCloud Data on the Web
By default, you can access your iCloud data on the web with pretty much any device. Even if you don’t have your iPhone or other Apple device with you, you can still go to iCloud.com and use your Apple ID to see important data like photos, notes, and the location of your devices.
If that sounds like too much data to be able to be accessed outside your Apple devices, you can now disable this by doing the following:
- Open the Settings app on your iPhone.
- Tap on your Apple ID at the top.
- Select iCloud.
- Scroll down to the bottom and toggle Access iCloud Data on the Web off.
You can easily switch this back on when you want to log into iCloud.com, but leaving it off adds an extra layer of security.
