Step 1: To start, go to appleid.apple.com and click Forgot Apple ID or password in the center of the page.
Step 2: You’ll be taken to a new page where you’ll have to enter your Apple ID or 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 really based on your personal preference.
Step 4: Choosing the email method prompts Apple to send instructions to the primary email address you used to begin this process, or a rescue email if you decided to make one. You’ll know the email has been sent when you see the “Email has been sent” page with a large, green check mark. If you can’t find the email, be sure to check your Spam, Junk, and Trash folders, or repeat the steps above to have the email sent again. Going with the security questions requires you to confirm your birthday and answer the aforementioned questions before you’re able to create a new password.
If you use two-factor authentication
If you set up and enabled two-factor authentication — which is different from two-step verification — resetting your password will be even easier, as you’ll be able to reset your password directly from your trusted iPhone, iPad, iPod Touch, or from the Apple ID account page. If you’re unsure if you have any trusted devices, don’t be; when you set up two-factor authentication, you created trusted devices. All iOS devices will also need to have a passcode enabled.
Using your iOS device
Step 1: Go to Settings > [your name] > Password & Security.
