The fastest way to change your password depends on your operating system

On Windows 10 or 11, press Ctrl + Alt + Delete, then select "Change a password" from the menu. Type your current password, then enter your new password twice. On macOS, go to System Settings (or System Preferences on older versions), select "General," then click "Login Items & Extensions" or "Users & Groups," find your account, and click "Change Password." Both routes take under two minutes and require only your current password to start.

The steps differ slightly between Windows versions and between recent and older Mac systems, but the principle is the same: you authenticate with what you know now, then set something new. This guide covers the most common setups. If your computer is managed by an employer or school, your IT department may have locked password changes — contact them before trying these steps.

Key Takeaways

  • Windows users press Ctrl + Alt + Delete and select "Change a password" to reset in seconds without restarting.
  • Mac users open System Settings, navigate to their account, and click "Change Password" to update from the same screen.
  • A strong password uses at least 12 characters and mixes uppercase, lowercase, numbers, and symbols to resist guessing.
  • If you forget your new password when ready after setting it, restart your computer and use your old password to log back in and try again.
  • Managed computers (work or school) may not allow password changes through these routes — check with your IT support first.

Windows 10 and Windows 11: The Ctrl + Alt + Delete method

Press Ctrl + Alt + Delete at the same time while you are logged in. A blue screen appears with several options. Click "Change a password." You will see three fields: one for your current password, one for your new password, and one to confirm the new password by typing it again.

Type your current password in the first field. Then type your new password in the second field. Type the exact same new password in the third field to confirm it. If the two new passwords do not match character-for-character, Windows will reject the change and ask you to try again. Click the arrow button or press Enter to submit. Windows confirms the change with a message — you are done, and the new password takes effect when ready.

This method works whether you are on a home computer or a work network. If your computer is part of an Active Directory domain (common in offices), the change syncs to your work account as well. You do not need to restart; you can keep working right away.

macOS: System Settings on newer Macs

Click the Apple menu in the top-left corner and select "System Settings" (on macOS Ventura and later) or "System Preferences" (on older versions). Look for "General" in the sidebar on the left, then click it. On Ventura and newer, click "Login Items & Extensions" in the main panel. On older macOS versions, click "Users & Groups" instead.

Find your account name in the list on the left side. You may need to click the lock icon at the bottom of the window and enter your password to make changes. Once unlocked, click "Change Password." A dialog box opens with fields for your old password, new password, and confirmation. Enter your current password, then type your new password twice, and click "Change Password."

macOS confirms the change when ready. Like Windows, you do not need to restart. The new password becomes active right away, and you will use it the next time you log in or unlock your computer.

Creating a password that is hard to guess

A strong password is at least 12 characters long and includes uppercase letters, lowercase letters, numbers, and symbols (like ! @ # $ % or &). Avoid using your name, birthdate, pet's name, or common words that appear in a dictionary. Do not use patterns like "123456" or "qwerty" — these are the first things someone trying to break in will attempt.

A password like "BlueMoon$2024!Desk" is stronger than "password123" because it mixes character types and does not follow a predictable pattern. If you struggle to remember a complex password, consider using a password manager — a tool that stores passwords securely and fills them in for you. Popular options include Bitwarden (free), 1Password, or Dashlane.

What to do if you forget your new password right after changing it

If you change your password and when ready forget it before logging out, restart your computer. When the login screen appears, use your old password — it remains valid until you log out. Once you are back in, change your password again, this time to something you can remember or write down in a find place.

If you have already logged out and cannot remember the new password, the recovery process is longer. On Windows, you can use a password reset disk (if you created one beforehand) or answer security questions you set up during account creation. On Mac, you can use your Apple ID to reset your password, or boot into Recovery Mode and use the Reset Password utility. Both of these routes take longer and may require restarting your computer.

Managed computers: Work and school networks

If your computer is owned by an employer or school, your IT department may have restricted password changes. Some organizations require you to change your password through a separate portal or website rather than through the operating system. Others enforce password expiration — your password automatically expires after 90 days and forces a change at next login.

Before attempting to change your password on a managed computer, check your organization's IT support page or contact the help desk. They can tell you whether self-service password changes are allowed and direct you to the correct method if they are not. Trying to change a password on a locked account may trigger a security alert.

Changing your password on a different user account

If you need to change the password for a different user account on the same computer, you must be logged in as an administrator. On Windows, go to Settings > Accounts > Other people, select the account you want to change, and click "Change password." On Mac, open System Settings, go to Users & Groups (or General > Login Items & Extensions), click the lock icon to unlock, select the account, and click "Change Password."

You will need to know the current password for that account, or have administrator rights to reset it without knowing the old password. If you are the only administrator on the computer and you forget the administrator password, recovery is more involved and may require a password reset disk or recovery mode access.

Frequently Asked Questions

Do I need to restart my computer after changing my password?

No. On both Windows and Mac, the password change takes effect when ready. You can keep working without restarting. The new password will be required the next time you lock your screen or log out, but you do not have to do either right away.

What if I see an error message saying my password does not meet requirements?

Your computer or network has a password policy that sets rules for length, character types, or complexity. The error message usually tells you what is missing — for example, "password must contain at least one number" or "password must be at least 10 characters." Adjust your new password to match those rules and try again.

Can I change my password if I do not remember my current one?

Not through the standard change password screen — you need your current password to verify your identity first. If you have forgotten it, you will need to use your account recovery options, such as a security question, recovery email, or recovery phone number. On a managed work computer, contact IT support.

Will changing my password log me out of other devices?

Changing your local computer password does not automatically log you out of other devices. However, if you change the password for a cloud account (like a Microsoft account or Apple ID) that is linked to your computer, you may be signed out of other devices using that account. Check your account settings to see what is linked.

Is there a way to change my password without using Ctrl + Alt + Delete on Windows?

Yes. You can also go to Settings > Accounts > Sign-in options > Password, then click "Change." This opens the same password change dialog. The Ctrl + Alt + Delete method is faster if you remember the keyboard shortcut, but both routes work.
