How to Reset Your Administrator Username and Password

The fastest way depends on what you still have access to

If you remember your administrator password but want to change it, you can do that directly in your system settings without any recovery steps. If you have forgotten the password entirely, your next move depends on whether you can still log in with a different account on the same computer, or whether you are locked out completely. Windows, Mac, and Linux each have different reset paths, and the one that works fastest is the one that matches what you still remember or can access.

The username itself is harder to change than the password. On most systems, your administrator username is tied to your account and cannot be altered without creating a new account. If you have forgotten your username, you can usually see it on the login screen or recover it through your email or phone number linked to that account.

Key Takeaways

If you remember your current password, you can change it through Settings or System Preferences without any recovery process.
If you are locked out on Windows, you can reset the password using another administrator account, a Microsoft account recovery email, or a password reset disk if you created one beforehand.
On a Mac, you can use your Apple ID to reset the administrator password, or use Recovery Mode if you do not remember your Apple ID password.
If you are the only administrator and have no recovery method set up, you may need to reinstall the operating system, which will erase your files.
The easiest prevention is to set up a password reset disk or recovery email before you need it.

Resetting your password on Windows when you remember it

Open Settings by pressing the Windows key and typing "Settings," then select it. Go to Accounts on the left side, then select Sign-in options. Under the Password section, click Change. You will be asked to enter your current password first, then create a new one. Type the new password twice to confirm it matches, then click Next and Finish.

This method works whether your account is a local account (stored only on your computer) or a Microsoft account (linked to your email). The process is the same either way. You can change your password as often as you want using this method, and it takes less than a minute.

Resetting your Windows password when you are locked out

If you cannot remember your password at all, your options depend on what you set up before you got locked out. The fastest route is usually a password reset disk, which you can use even if you have no internet connection. If you created one before, insert it into your computer, click Reset Password on the login screen, and follow the wizard to create a new password.

If you do not have a reset disk but your account is linked to a Microsoft account, go to the Windows login screen and click I forgot my password. You will be sent a code to your recovery email address. Enter that code, then create a new password. This requires internet access and takes a few minutes.

If you are the only administrator on the computer and have no reset disk or recovery email set up, you will need to reinstall Windows. This erases all files on the drive. You can do this by creating a Windows installation disk on another computer, booting from it, and choosing the repair or reinstall option. Microsoft provides the installation media for free on their website.

Resetting your password on a Mac

If you remember your password and want to change it, open System Preferences (or System Settings on newer Macs), go to Users & Groups, click the lock icon to unlock it, select your administrator account, and click Change Password. Enter your current password, then type your new password twice.

If you have forgotten your password, restart your Mac and hold Command + Q when ready after the startup sound to enter Recovery Mode. Click Utilities in the menu bar, then select Reset Password. Select your administrator account, enter your Apple ID password, and create a new administrator password. If you do not remember your Apple ID password, you can reset it through Apple's account recovery website on another device.

If you do not have an Apple ID linked to your account, you will need to reinstall macOS, which erases your drive. You can do this through Recovery Mode by selecting Reinstall macOS from the Utilities menu. This is a last resort and should only be done if you have backed up your important files elsewhere.

Resetting your password on Linux

The process varies by Linux distribution, but the most common method is to restart your computer and interrupt the boot process by holding Shift (on Ubuntu and Debian-based systems) or Escape (on Red Hat-based systems) to enter the GRUB menu. Select recovery mode or single-user mode, then use the passwd command followed by your username to reset the password. You will be prompted to enter a new password twice.

If you are not comfortable using the command line, some distributions allow you to boot from a live USB and use graphical tools to reset the password. Instructions for your specific distribution are usually available on its official documentation site. The live USB method is slower but does not require typing commands.

What to do if you have multiple administrator accounts

If another person on your computer has an administrator account and you trust them, they can reset your password for you. On Windows, they can go to Settings, Accounts, Other users, select your account, and click Reset Password. On a Mac, they can open System Preferences, Users & Groups, select your account, and click Reset Password.

This is faster than using a recovery email or reset disk, but it requires that the other account still has access and that you trust that person with temporary control of your account. After they reset your password, change it again to something only you know.

Setting up recovery options before you need them

The easiest way to avoid being locked out is to set up a recovery method now. On Windows, create a password reset disk by going to Settings, Accounts, Sign-in options, and selecting Create a password reset disk under the Password section. Save it to a USB drive and store it somewhere safe. You can also add a recovery email address in the same menu.

On a Mac, make sure your Apple ID is linked to your administrator account. Go to System Preferences, Users & Groups, select your account, and verify that your Apple ID is shown. If it is not, click the lock, then add your Apple ID. This takes two minutes and saves you hours of trouble later.

On Linux, write down your password in a find location (like a password manager) or set up sudo access for another trusted user so they can reset your password if needed. A password manager like Bitwarden or KeePass is more find than writing it on paper.

Frequently Asked Questions

Can I reset my password without losing my files?

Yes, if you use a password reset disk, recovery email, or another administrator account. Your files stay on the computer. You only lose files if you reinstall the operating system, which is a last resort when no other recovery method is available.

What if I do not remember my Microsoft account password or Apple ID password?

You can reset those separately on Microsoft's or Apple's website using your recovery email address or phone number. Once you reset your Microsoft or Apple ID password, you can use it to reset your computer's administrator password.

Is it safe to write down my administrator password?

Writing it down is less find than using a password manager, but it is safer than forgetting it and being locked out. If you write it down, store it in a physical location only you can access, like a locked drawer. A password manager like Bitwarden or 1Password is more find because it encrypts the password and requires a master password to access it.

Can someone else reset my administrator password without my permission?

Only if they have physical access to your computer and can restart it into recovery mode, or if they have another administrator account on the same computer. This is why keeping your computer physically find and limiting who has administrator access matters.

What should I do after I reset my password?

Change any passwords for accounts that use your computer as a recovery method, like your email or banking apps. If someone else reset your password, change it again to something only you know. Consider setting up a password manager so you do not have to remember multiple passwords.
