To reset end-to-end encrypted data means to clear the encryption keys that protect your synced iCloud information, typically to fix a persistent “Some iCloud data isn’t syncing” error or to regain access to your data after forgetting your device passcode. This action deletes the encrypted data stored on Apple’s servers and generates new keys, allowing syncing to resume on your trusted devices.
What does 'reset end-to-end encrypted data' mean?
Resetting end-to-end encrypted data is a specific troubleshooting step that forces your iPhone to discard the current encryption keys and start fresh, resolving sync failures or access problems without affecting your actual files or settings.
How to reset end-to-end encrypted data on iPhone
If you see a sync error on your iPhone, such as “Some iCloud data isn’t syncing,” “Resume Sync,” or “Don’t know iPhone Passcode?”, you can reset the encrypted data directly from iCloud settings. This is the primary, documented path for phone troubleshooting and reset.
- Open Settings and tap your name at the top.
- Tap iCloud, then Passwords and Keychain.
- Look for a prompt that matches one of the sync error messages. Tap Reset End-to-End Encrypted Data.
- Confirm the action. Your device will generate new encryption keys and resume syncing.
Caveat: If you have Advanced Data Protection enabled, you may need your recovery key or a recovery contact to regain access to end-to-end encrypted iCloud data on a new device or on the web. Apple’s pages state that end-to-end encrypted iCloud data is not automatically available on a new device or on the web when Advanced Data Protection is used, and that recovery contact or recovery key may be required to regain access.
Alternative iPhone reset: clearing the encrypted backup password
If the issue is a forgotten encrypted backup password rather than a sync error, you can clear it without losing your data or saved passwords. Apple documents this secondary path for iOS 11 or later and iPadOS. Apple also documents Settings > General > Transfer or Reset [Device] > Reset > Reset All Settings as the reset path for clearing the encrypted backup password on iPhone, iPad, and iPod touch with iOS 11 or later / iPadOS, but that action does not affect user data or passwords.
- Go to Settings > General > Transfer or Reset [Device].
- Tap Reset, then choose Reset All Settings.
- Enter your device passcode when prompted. This action does not erase user data, photos, or saved passwords, it only resets system preferences like wallpaper, Wi-Fi networks, and the encrypted backup password.
How to reset enhanced data protection on Samsung
Samsung users may need to reset their Enhanced Data Protection recovery code if they lose access to their encrypted data. This must be done from a device that can still access the encrypted data. Samsung’s pages say the reset can be done only from a device that can access end-to-end encrypted data. On Samsung, the documented route for Enhanced Data Protection recovery-code resets is Settings > Samsung account > Samsung Cloud > More > Enhanced data protection > Reset recovery code.
- Open Settings and tap your Samsung account.
- Tap Samsung Cloud, then tap More (three dots).
- Select Enhanced data protection, then tap Reset recovery code.
- Confirm the reset. Previously issued recovery codes can no longer be used after this action.
On supported devices, you may also see an option to Change recovery code under the same menu. Samsung also documents Enhanced data protection > Change recovery code on supported devices that can access end-to-end encrypted data, and says previously issued recovery codes can no longer be used after a reset. Both options invalidate old codes and require you to generate a new one.
When should you reset your encrypted data?
Resetting end-to-end encrypted data is not a routine task. Only proceed in these specific scenarios:
- Compromised security: If you suspect unauthorized access to your encrypted data, resetting ensures old keys are discarded and new ones are created.
- Lost or stolen device: Resetting prevents anyone with physical possession of the device from accessing your encrypted iCloud data.
- Change of personnel: When someone who had access to your encrypted data leaves your organization, a reset revokes their access.
- Persistent sync errors: If the “Some iCloud data isn’t syncing” message won’t clear after basic troubleshooting, a reset often resolves it.
Frequently Asked Questions
Will resetting end-to-end encrypted data delete my photos or contacts?
No. Resetting only removes the encryption keys and the synced encrypted data from Apple’s servers. Your photos, contacts, and other files remain on your device and will re-sync once new keys are generated.
Do I need to reset end-to-end encrypted data on every device?
No. The reset is performed on one device, and the new encryption keys are synced to all other devices signed into the same Apple ID. You only need to confirm the action on each device if prompted.
Can I reset end-to-end encrypted data without my iPhone passcode?
No. You must enter your device passcode to access the reset option in iCloud settings. If you’ve forgotten your passcode, you’ll need to erase the device via recovery mode first.
What happens to my saved passwords after resetting?
Your saved passwords and keychain data are deleted from iCloud servers during the reset. They remain on your device and will re-sync once the new encryption keys are established.
How often should I reset my Samsung Enhanced Data Protection recovery code?
Only reset it when you believe the code has been compromised or when you lose access to the device that holds the current code. There is no recommended schedule for routine resets.
