Someone Using Your Apple ID? Stop Them Now

📅 8 July 2026 ⏱ 4 min read 🍎 Apple

That sinking feeling when something's not right

You get an email saying your Apple ID was used to sign in from a city you've never visited. Or your iPhone asks you to verify a device you don't recognise. That queasy feeling is your gut telling you something is wrong — and it's right to listen. Your Apple ID is the master key to your photos, messages, iCloud backups, and any payment cards you have stored. If someone else has it, they have a lot.

The good news: Apple gives you real tools to deal with this. The key is moving quickly and methodically.

Signs your Apple ID has been compromised

Step 1 — Check which devices are signed in right now

On your iPhone or iPad: go to Settings → [your name] and scroll down. You'll see every device currently signed in to your Apple ID. On a Mac, go to Apple menu → System Settings → [your name]. On the web, visit appleid.apple.com.

Tap any device you don't recognise and choose Remove from Account. Do this before you change your password — otherwise the intruder gets an alert and may act faster than you.

Step 2 — Change your Apple ID password immediately

Go to Settings → [your name] → Sign-In & Security → Change Password. Use a strong, unique password — not one you use anywhere else. A 14-character mix of letters, numbers, and symbols is ideal. Don't use your name, birthday, or anything obvious.

Changing your password signs out all devices automatically (except the one you're using). That's exactly what you want.

Step 3 — Turn on two-factor authentication if it isn't on already

Two-factor authentication (2FA) means that even if someone has your password, they still can't sign in without a six-digit code sent to one of your devices. It's the single most effective thing you can do to protect your Apple ID.

Go to Settings → [your name] → Sign-In & Security → Two-Factor Authentication and switch it on. You'll need to confirm a trusted phone number. Do it now if you haven't already.

Step 4 — Check for damage

Once you've secured the account, look for what the intruder may have done:

When to get help

If your Apple ID password has already been changed by the intruder and you're locked out, the recovery process is more involved. Apple's account recovery can take days, and it requires you to prove your identity carefully — which is actually reassuring, because it protects you from the same attack.

If you're locked out, or if you suspect a device in your home has been set up to monitor you, don't try to handle it alone. Bring the device in — or read our guide on other signs your device may be compromised — and we'll work through it with you confidentially. We're based in Pinar de Campoverde and help residents across Pilar de la Horadada and the wider Costa Blanca.

Quick summary: what to do right now

  1. Check which devices are signed in — remove any you don't recognise.
  2. Change your Apple ID password immediately.
  3. Turn on two-factor authentication.
  4. Check your purchase history and report any unauthorised charges.
  5. If you're already locked out — get help promptly.

FAQ

How do I see what devices are signed in to my Apple ID?

On iPhone or iPad, go to Settings and tap your name at the top. Scroll down and you'll see a list of every device using your Apple ID. On a Mac, go to Apple menu → System Settings → your name. You can remove any device you don't recognise directly from that screen.

Someone changed my Apple ID password and I'm locked out — what do I do?

Go to iforgot.apple.com and start Apple's account recovery process. You'll need access to your trusted phone number or a recovery key if you set one up. If you don't have either, Apple's account recovery can help but takes time to verify your identity. Come and see us if you need help working through it.

Will changing my Apple ID password sign out all my other devices?

Yes — changing your Apple ID password automatically signs out every device except the one you used to make the change. That's one of the most effective ways to immediately kick out an unauthorised user.

Can someone spy on me through my Apple ID without me knowing?

If someone is signed in to your Apple ID, they can potentially see your iCloud Photos, location via Find My, messages synced to iCloud, and more. Following the steps in this post — especially removing unknown devices and changing your password — will stop that access.
