Find out Apple ID via apple.com – you have to do this
- Open this page from Apple, press "Sign in" and click on "Forgot Apple ID or password" under the input fields. On the next page, click again under the input field on "Forgot your Apple ID?".
- Enter your first and last name and your email address. Apple then uses this data to search for your Apple ID.
- After clicking Next, two options will appear to confirm your identity. Either answer a security question or have a confirmation link sent to you by email.
- Once you have confirmed your identity, your Apple ID will be displayed in bold type. For security, you must then set a new password.
