But it is not possible as the old one has been lost by her. So the only choice left for me is to reset end-to-end encrypted data. What is encrypted data on iPhone? What does this mean? Will it remove all my data on my iCloud Backup?”

What kind of data you’ll lose when you choose to reset end-to-end encrypted data on iPhone?

End-to-end Encrypted Data is another security feature developed by Apple, which gives the maximum level of protection to keep any form of data safe. With the use of a key, data will be safeguarded before being delivered to another user in encrypted form. It also necessitates two-factor authentication on a different trusted device. End-to-end Encrypted data is accessible across all types of devices owned by the same company, such as iPhone, iPad, and Mac.

When you are asked to reset end-to-end encrypted data on iPhone, fortunately, it won’t erase all data on your old iPhone. All your photos, music, and other personal stuff stay for your access. According to Apple, the data that is reset is as follows.

  • Apple Card transactions
  • Health data
  • Home data
  • Keychain
  • Maps Favorites, Collections, and search history
  • Memoji
  • Messages in iCloud
  • Payment information
  • QuickType Keyboard learned vocabulary
  • Safari History, Tab Groups, and iCloud Tabs
  • Screen Time
  • Siri information
  • Wi-Fi passwords
  • W1 and H1 Bluetooth keys

Note: For Messages in iCloud, your backup includes a copy of the key safeguarding your messages if you have iCloud Backup enabled. If you lose access to your Keychain or trusted devices, you’ll be able to restore your messages.
