How do I lock a lost phone from a computer?
Answer
Yes — both major platforms have a website that does this. Sign in with the same account the phone uses, select the device, and choose the lock or lost-mode option. That locks the screen, shows a message with a contact number, and keeps reporting its location.
Before you start: stop right away if…
- Erasing a device remotely ends its location reporting, so it cannot be tracked afterwards.
- Messages claiming your lost phone was found and asking you to sign in are a very common phishing tactic. Only use the official site.
- Do not travel to an unfamiliar location shown on the map. Report it instead.
Follow these steps
Open the find-my-device website
On the computer, go to the official find-my-device site for your phone's platform and sign in with the same account.
You should see: A map lists your devices.
Select the missing phone
Choose it from the device list and check whether the location is live or last known.
You should see: You can see where it was most recently.
Lock it and add a message
Choose the lock or lost-mode option, and add a phone number where you can be reached. This displays on the locked screen.
You should see: The phone locks and shows your message.
Make it ring if it may be nearby
Use the play sound option — it works even if the phone was on silent.
You should see: The phone chimes and can be located by ear.
Erase only as a last resort
Erasing removes everything and stops location reporting, so leave it until you have given up recovery.
You should see: The phone's data is protected once you decide.

Extra tips
What to look for: Whether the map shows a live position or only a last known one with a time. A moving position means someone has it.
Before you change anything: Have the account password ready, and any second-factor method, since these sites always ask.
