Reset Your iMac Password Using Your Apple ID
If you have forgotten your iMac login password, the fastest way back in is through your Apple ID. When you reach the login screen, click the question mark icon below the password field—this opens password reset options. Select "Reset it with your Apple ID" and enter the Apple ID and password associated with your Mac. Your system will then let you create a new login password without erasing anything on your computer.
This method works only if you set up an Apple ID when you first configured your iMac, or if you added one in System Settings afterward. If you do not remember your Apple ID password, you will need to reset that first through iforgot.apple.com before you can use this route to unlock your Mac.
After you create a new password, your Mac will ask whether you want to update your keychain—the encrypted storage where your Mac keeps saved passwords for websites and apps. You can choose to update it now or skip this step and update it later.
Key Takeaways
- The question mark icon on your iMac login screen opens a password reset menu that lets you create a new password using your Apple ID.
- You must know your Apple ID and its password to use this method; if you do not, reset your Apple ID first at iforgot.apple.com.
- Resetting through Apple ID does not erase your files or applications—you keep everything on your computer.
- If you do not have an Apple ID linked to your iMac, you will need to use Recovery Mode or contact Apple Support for other options.
Use Recovery Mode if You Have No Apple ID on File
If your iMac was never set up with an Apple ID, or if you cannot remember the one you used, you can reset your password through Recovery Mode. Shut down your iMac completely, then turn it back on while holding Command + R. Keep holding until you see the Apple logo or a spinning globe—this loads Recovery Mode, a special startup environment separate from your normal system.
Once Recovery Mode opens, you will see a menu with several options. Click "Utilities" in the menu bar at the top, then select "Terminal." A black text window will open. Type resetpassword and press Enter. This launches the Reset Password utility, which will show you a list of user accounts on your Mac. Select your account, enter a new password twice to confirm it, and click "Save."
After you save, close the Reset Password window and restart your iMac normally. You can now log in with your new password. This method also does not erase your files or settings.
Create a New Admin Account if You Cannot Access Recovery Mode
If Recovery Mode will not open, or if the Reset Password utility does not recognize your account, you have one more option: create a new administrator account and use it to reset the password on your original account. This requires an iMac running macOS Big Sur or newer.
Restart your iMac and hold Command + Q when ready after the startup sound. This opens the Setup Assistant, which normally runs only when you first turn on a new Mac. Follow the prompts to create a new administrator account with a password you choose. Once setup finishes, log in with this new account.
Open System Settings, click "General" in the sidebar, then select "Users & Groups" (or "Users & Groups" under the System section, depending on your macOS version). Click the lock icon at the bottom left and enter your new admin password. Now you can select your original account and click the gear icon to reset its password. After you change it, you can delete the temporary admin account if you wish.
What to Do if Your Mac Will Not Start at All
If your iMac will not turn on, will not complete startup, or shows a folder with a question mark when you power it on, the password reset methods above will not work until the Mac is running again. In these cases, the problem is usually a hardware or software issue rather than a forgotten password.
Try restarting your iMac and when ready holding Command + Option + R to start Internet Recovery Mode, which downloads system files from Apple's servers. This can sometimes repair startup problems. If that does not work, or if your Mac still will not start, contact Apple Support or visit an Apple Store—a technician can diagnose whether the issue is a hard drive failure, a corrupted system file, or something else that requires professional repair.
Prevent Lockouts by Storing Your Apple ID Securely
The easiest way to avoid a forgotten password is to make sure your Apple ID is set up on your iMac and that you store your Apple ID password somewhere you can find it. Write it down in a physical notebook kept in a safe place, or use a password manager like 1Password or Bitwarden that encrypts and stores your passwords.
You can also set up Touch ID or Face ID on newer iMacs, which lets you unlock your computer with your fingerprint or face instead of typing a password every time. This reduces the chance you will forget the password because you use it less often. To enable this, open System Settings, click "Touch ID" or "Face ID," and follow the setup steps.
If you have family members or colleagues who share your iMac, consider setting up a separate user account for each person rather than sharing one login. This way, if one person forgets their password, it does not lock everyone out of the computer.
When to Contact Apple Support Instead
If you have tried the methods above and none of them work, or if your iMac shows an error message you do not recognize, contact Apple Support. You can reach them through support.apple.com, by phone at 1-800-MY-APPLE, or by visiting an Apple Store in person.
Have your iMac serial number ready—you can find it by clicking the Apple menu in the top left corner and selecting "About This Mac." Apple Support can verify your identity and walk you through additional troubleshooting steps, or they can help you understand whether your Mac needs hardware service.
Frequently Asked Questions
Will resetting my password erase my files?
No. Resetting your password through Apple ID, Recovery Mode, or the Reset Password utility does not erase any files, applications, or settings. Your data stays on the computer. Only the password itself changes.
What if I do not remember my Apple ID email address?
Go to iforgot.apple.com and look for the option to search for your Apple ID using your phone number or full name. Apple will help you locate the email address associated with your account, then you can reset the password.
Can I reset my password without restarting my Mac?
If you are already logged in, you can change your password without restarting. Open System Settings, click "General," then select "Users & Groups." Click the lock icon, enter your current password, select your account, and click "Change Password." This is different from a reset—you need to know your current password to use this method.
How long does it take to reset my password through Recovery Mode?
The process usually takes five to ten minutes from the moment you restart your Mac. Most of that time is waiting for Recovery Mode to load. The actual password reset takes less than a minute.
What if the Reset Password utility does not show my account?
This sometimes happens if your account is hidden or if Recovery Mode is not loading correctly. Try restarting again and holding Command + R longer before the Apple logo appears. If the account still does not show, contact Apple Support—this may indicate a deeper system problem.
