If you think your Apple ID has been compromised

Are you concerned that an unauthorised person might have access to your Apple ID? These steps can help you find out and regain control of your account.

Signs your Apple ID has been compromised

Your Apple ID might be compromised if you receive an account notification from Apple for a change you didn't make, or if you notice account details or changes you don’t recognise. For example:

• You receive an email or notification that your Apple ID was used to sign in to a device you don't recognise or did not sign in to recently (for example, "Your Apple ID was used to sign in to iCloud on a Windows PC").
• You receive a confirmation email from Apple that your Apple ID password was changed or your account information was updated, but you don’t remember making any changes.
• Your device was locked or placed in Lost Mode by someone other than you.
• You see messages you didn't send, or items you didn’t delete.
• You see charges or notices for purchases that you didn't make. Learn what to do if you see an unfamiliar iTunes Store or App Store charge on your credit or debit card statement.
• Your password no longer works, or it might have been changed or locked.
• You don't recognise some or all of your account details.

If you received an email, text message or phone call that you're not sure is valid or you think might be phishing, here are some tips to help determine its legitimacy.

Gain control of your Apple ID

If you think your Apple ID is compromised, use these steps to gain control of it and review your account information:

1. Sign in to your Apple ID account page. If you can't sign in or you receive a message that the account is locked when you try to sign in, try to reset or unlock your account.
2. Change your Apple ID password and choose a strong password.
3. Review all the personal and security information in your account. Update any information that isn't correct or that you don’t recognise, including:

• • Your name.
  • Your primary Apple ID email address.* If you need to change your email address, update the features and services that you use with Apple ID, so that each one is using your updated Apple ID.
  • All alternative email addresses, rescue email addresses and phone numbers. 
  • The devices that are associated with your Apple ID, if you've already set up two-factor authentication.
  • Security questions and answers. If you think they might be easy to guess, you should change your security questions.

1. Check with your email address* provider to make sure that you control every email address associated with your Apple ID. If you don't control the email addresses associated with the Apple ID, you should change the password for the email address or use a different email address. 
2. Set up two-factor authentication for your Apple ID. This additional security feature is designed to prevent anyone from accessing your account, even if they know your password.

I'm glad you changed it. Everything should be good now.
