When your iPhone is lost or stolen

A woman uses a laptop at a bright shared workspace.

What to do

Mark your iPhone as lost

You can mark your iPhone as lost from any phone or computer. Lost Mode locks your iPhone and stops Apple Pay on the lost iPhone. When you get your iPhone back, enter your passcode on your iPhone to turn off Lost Mode.

  1. In a web browser, go to icloud.com/find.
  2. Sign in to your Apple Account. If you’re asked for a verification code, select Find Devices at the bottom of the sign-in window instead. Apple says you don’t need the code to mark your iPhone as lost.
  3. In the list of devices, select your iPhone. The map shows where your iPhone is, and you can play a sound on your iPhone from there.
  4. Select Mark As Lost.
  5. Follow the steps on the screen.

If you lost your iPhone, you can add a message and a number where you can be reached, such as a family member’s phone. Both show on your iPhone’s Lock Screen, so whoever finds your iPhone can call you. If your iPhone was stolen, leave out your phone number and message. Apple says the person with your iPhone could use your details to trick you, for example with a fake message from Apple. Apple never calls or messages you to say your iPhone was found.

If your iPhone is off or offline, you see Pending until your iPhone is back online. Lost Mode starts then.

Was your iPhone stolen? Or does the map show your iPhone at a place you don’t know? Then Apple says not to try to get your iPhone back yourself. Contact your local police instead.

You can also mark your iPhone as lost in the Find My app on another Apple device, or on a family member’s iPhone. Apple’s steps for a lost iPhone

Change your Apple Account password

After you mark your iPhone as lost, change your Apple Account password if you think someone saw or knows your iPhone passcode. Change your Apple Account password right away too if your iPhone isn’t in the Find My list.

  1. On another Apple device that’s signed in to your Apple Account, open the Settings app.
  2. Tap your name, then Sign-In & Security.
  3. Tap Change Password.
  4. Follow the steps on the screen.

On a Mac, the same steps start in System Settings. No such device? On any phone or computer, go to account.apple.com and sign in. Then choose Sign-In and Security, then Password. Apple’s steps to change your password

If you can’t get your iPhone back

  1. Report your iPhone to your local police. The police may ask for your iPhone’s serial number.
  2. Ask your phone carrier to suspend your account.
  3. Check your Apple Account on another Apple device signed in to your account, or at account.apple.com. Look for an email address, phone number or device you don’t know. If you find one, change your Apple Account password.
  4. If AppleCare+ with Theft and Loss covers your iPhone, file a claim for a replacement.
  5. If you don’t expect to get your iPhone back, erase your iPhone. At icloud.com/find, select your iPhone, then select Erase This Device. Erasing can’t be undone.

Even after you erase your iPhone, don’t select Remove This Device in Find My. While your iPhone stays in Find My, Activation Lock stays on, so nobody can set up your iPhone again without your Apple Account password. Apple’s steps if your iPhone was stolen

Later: turn on Stolen Device Protection

Stolen Device Protection helps if someone takes your iPhone and knows your passcode. With Stolen Device Protection on, away from places like home or work, the passcode alone can’t turn off Lost Mode. Your iPhone asks for Face ID or Touch ID instead. Turn on Stolen Device Protection on your next iPhone, or on your lost iPhone if you find it.

  1. Open the Settings app.
  2. Tap Face ID & Passcode. On an iPhone with a Home button, tap Touch ID & Passcode.
  3. Enter your passcode.
  4. Tap Stolen Device Protection.
  5. Turn on Stolen Device Protection.

Stolen Device Protection needs iOS 17.3 or later. If you don’t see Stolen Device Protection, set up Face ID or Touch ID first. If you set up your new iPhone from the iCloud Backup of your lost iPhone, your Stolen Device Protection setting comes back too.

Underlock is coming soon to the App Store. Here’s how it will work.

What Underlock does

  • Your passcode doesn’t open your vault. Your vault opens with your own pattern, not your iPhone passcode or Face ID.
  • Nothing to see without your pattern. Anyone who opens Underlock without your pattern finds only the pattern screen.
  • Locks as you leave. By default, your vault locks the moment you leave Underlock.

Questions people ask

No. Your vault opens with your own pattern, not your iPhone passcode or Face ID. Without your pattern, Underlock shows only the pattern screen.

Apple says to erase your iPhone only if you don’t expect to get your iPhone back, because erasing can’t be undone. Erasing your iPhone also erases your vault on that iPhone.

Mark your iPhone as lost, then change your Apple Account password, as in the steps above. Your passcode doesn’t open your vault.

Enter your passcode on your iPhone to turn off Lost Mode. With Stolen Device Protection on, you may need Face ID or Touch ID. Then open Underlock and draw your pattern, as before.

Yes. Underlock is free forever: one vault, no file limit. If the free plan ever changes, you keep the plan you started with. More vaults come with Pro, Underlock’s paid plan.

Your vault keeps a lock of its own

Free for one vault, with no file limit. No account, no email.

For iPhone with iOS 17 or later.

Coming soon to the App Store
