Being locked out of your phone can be a safety risk in an emergency. Consider having a backup way to contact emergency services.
Locking You Out of Your Devices
Someone locks you out of your own phone, tablet, or computer — by changing the passcode, using remote lock features, or triggering factory resets.
What You Might Notice
Your device passcode suddenly stops working
The password, PIN, or biometric you set has been changed.
Your device has been remotely wiped or reset
All your data, photos, and apps are gone.
You receive a message saying your device is locked
Features like 'Find My iPhone' or 'Find My Device' can be used to remotely lock a device.
What You Can Do
Contact your device manufacturer's support
Apple, Samsung, and Google all have processes for recovering locked devices.
Use a different device to secure your cloud accounts
If your phone is locked, secure your iCloud, Google, or Microsoft accounts from another device immediately.
Keep your cloud account credentials separate and private
The person who controls your iCloud or Google account can remotely control your device.
