If your Apple ID is locked
If you or someone else enters your password, security questions, or other account information incorrectly too many times, your Apple ID automatically locks to protect your security and you can't sign in to any Apple services. You can unlock your Apple ID after you verify your identity.
If your Apple ID is locked for security reasons, you might see one of these alerts:
- “This Apple ID has been disabled for security reasons”
- "You can't sign in because your account was disabled for security reasons"
- "This Apple ID has been locked for security reasons"
When you see one of these alerts, you can go to
iforgot.apple.com to unlock your account with your existing password or to
reset your password. After multiple unsuccessful attempts to unlock your account, your Apple ID will remain locked and you can try again the next day.
If you use
two-step verification, you need to use your recovery key and a trusted device. And if you use
two-factor authentication, you need a trusted device or trusted phone number to unlock your Apple ID.
If you see a message that is different from the alerts above and you can't reset your password,
contact us for help.
