I’m going to answer the question you asked, then the question you might mean. The MAC address is the physical “serial number” of the network card in your device. It’s supposed to be unique worldwide. It’s only used by machines on your local netwo. Jul 07, 2020 While you'll be able to use the following method to bypass the login on most Macs, some Mac users will have enabled FileVault and/or a firmware password, making it impossible to hack the Mac without knowing the password (s). Keep in mind that the Mac user will know that someone accessed their computer due to the password change. If someone has access to your local network they may be able to do so without an IP address if they can get your MAC address. For remote hacking over an internet knowing the IP address is a necessary but not sufficient condition for access to the machine. If someone knows your IP address then they can scan your computer for open ports. This is not a comfortable situation. If attackers can upload some malware on your computer, then, at that point, you are hosed: they can see everything you see on your display, they can track all your key stroke, they can plunder your files, they might even switch your Webcam on and spy on your physical person.
Have you tried to log in to your Apple ID using your password? It is possible that the email you received may have been a phishing attempt rather than coming from Apple.

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 recognize. For example:
- You receive an email or notification that your Apple ID was used to sign in to a device you don't recognize 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 recognize 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:
- 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.
- Change your Apple ID password and choose a strong password.
- Review all the personal and security information in your account. Update any information that isn't correct or that you don’t recognize, 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 alternate 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.
- 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.
- 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.
* In China mainland and India, you can use your phone number as your Apple ID.
If you completed the steps above and think your account might still be compromised, contact Apple Support.

Know which Apple ID is signed in to your device
If you're signed in on your device with an Apple ID that you don't recognize, use these steps to sign out, then back in with a different Apple ID. To make sure that you're signed in to Apple IDs that only you control or trust, you can check the following settings on each of your devices:
iPhone, iPad, or iPod touch:
- Settings > [your name]
- Settings > [your name] > iTunes & App Store
- Settings > Messages > Send & Receive
- Settings > FaceTime
Mac:
- System Preferences > Apple ID
- System Preferences > Internet Accounts
- Messages > Preferences > Accounts
- Facetime > Preferences > Settings
- Mail > Preferences > Accounts
- Calendar > Preferences > Accounts
You should also check iCloud for Windows, your AirPort Time Capsule or other AirPort Base Station, and your Apple TV (for iCloud Photos or Home Sharing).
Make sure your Apple ID is secure
Because you use your Apple ID for so many Apple products and services, you should make sure that your Apple ID is as secure as possible. You should be the only person who knows your password and can sign in with your Apple ID. If someone you don’t know or don’t trust can sign in with your Apple ID, your account is not secure.

Your Apple ID might not be secure for the following reasons:
- Someone else created an Apple ID on your behalf, or you’re using an Apple ID that was already signed in when you received your device.
- You’re sharing an Apple ID with family or friends. Your Apple ID is your personal account. If you want to share purchases with a family member, use Family Sharing. With Family Sharing, you can share a calendar, photos, reminders, and more without sharing your Apple ID.
- You don’t recognize the Apple ID that is signed in on your device.
- You shared your password with someone else intentionally or unintentionally. For example, someone else selected your password for you, you told someone your password, or you entered your password on a phishing site.
- You don't have control of the email address or phone number associated with your Apple ID.
- Your password is weak or is compromised.
- You share your devices with someone else, your devices are not protected by a passcode, or your passcode is easy to guess.
How Do You Hack Passwords
If any of the above are true, you should reset your password as soon as possible and review your account information.
