Wait for the Phone to Reset
The phone will reboot and begin the reset process. This may take several minutes.
Reset Remotely (If Your Phone Is Lost or Stolen)

🔐 Additional Tips for Security
-
Enable Screen Locks: Always have a passcode, PIN, and/or biometric lock on your phone.
-
Keep Find My Device / Find My iPhone Enabled: Essential for remote wipes.
-
Remote Lock First: If you’re unsure about erasing right away, both Google and Apple let you lock the phone remotely to buy some time. This can be handy if you’re not 100% certain about if your phone is stolen, or just lost.
