How to reset your Apple ID password?
Step 1: To start, go to appleid.apple.com and click Forgot Apple ID or password in the center of the page. (Your password may automatically prefill the sign-in screen in a drop down menu, especially if you checked the Remember Me box, so look for it first and click to see if it works.)
Step 2: You’ll be taken to a page where you enter your Apple ID (in most cases, it is the primary email address for your Apple account), and then to a new page where you’ll enter your name and the email address associated with the account. Click Continue, then select I need to reset my password.
Step 3: You’ll now be able to choose how you want to reset your password, whether it be through email or by answering a set of security questions. Which option you choose is based on your personal preference.
