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 that appears. Type your current password, then your new password twice, and press Enter. The change takes effect when ready.

On Mac, go to System Settings (or System Preferences on older versions), select "General," then click "Login Items & Extensions" or "Users & Groups." Click the lock icon to unlock the settings, select your account, and click "Change Password." Enter your old password and your new one twice.

Both methods work whether you use a local account or a cloud-connected account. The process takes less than two minutes on either system.

Key Takeaways

  • Windows users can change their password in seconds using Ctrl + Alt + Delete without opening any settings menu.
  • Mac users access the password change through System Settings and must unlock the settings panel first.
  • Your new password takes effect when ready on both systems, and you will use it the next time you log in.
  • A strong password includes uppercase letters, lowercase letters, numbers, and symbols, and should not contain your username or common words.
  • If you forget your new password after changing it, recovery options depend on whether you set up a recovery email or phone number beforehand.

Windows: Step-by-step password change

Hold down Ctrl, Alt, and Delete at the same time. A blue screen will appear with several options. Click "Change a password" — it is usually the third option from the top. Do not click "Sign out" or "Lock" by mistake.

A dialog box will open asking for three passwords. In the first field, type the password you use right now to log in. In the second field, type your new password. In the third field, type that same new password again to confirm you did not make a typo. Click the arrow or press Enter.

Windows will tell you whether the change worked. If you see a message saying "Your password has been changed," you are done. If you see an error, the most common reason is that your new password does not meet the system's complexity rules — it may need to be at least 8 characters long and include uppercase letters, lowercase letters, and numbers.

Mac: Step-by-step password change

Click the Apple menu in the top-left corner and select "System Settings." On older Macs running Monterey or earlier, this menu item is called "System Preferences" instead. Look for "General" in the sidebar on the left, then click it.

In the General panel, find and click "Login Items & Extensions" (or "Users & Groups" on older versions). You will see a lock icon at the bottom of the window. Click it and enter your current password to unlock the settings. Once unlocked, click your user account name on the left side of the window.

Click the "Change Password" button. A new window will ask for your old password first, then your new password twice. Type carefully — you cannot see what you are typing. Click "Change Password" to finish. The change takes effect the next time you log in.

What makes a strong password you will actually remember

A strong password is at least 12 characters long and mixes uppercase letters, lowercase letters, numbers, and symbols like ! or #. Avoid using your username, your name, your birth year, or common words that appear in the dictionary. A password like "BlueMoon#2024" is easier to remember than a random string but still harder to guess than "password123."

One method that works well is to take a phrase you remember and use the first letter of each word, then add a number and symbol. For example, "I adopted my cat in 2019!" becomes "IamcI2019!" — something you can recall but others cannot guess.

Do not write your password down on a sticky note or in an unencrypted text file. If you struggle to remember passwords, consider using a password manager like Bitwarden or 1Password, which stores passwords securely and fills them in automatically.

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

On Windows, restart your computer and try logging in with your new password. If you typed it wrong during the change process, you may still be able to log in with your old password — the change does not always take effect if there was an error. If neither password works, you will need to use a recovery method.

Windows accounts linked to a Microsoft account can be recovered by visiting the Microsoft account recovery page from another device and resetting your password there. Local accounts without a recovery email are much harder to recover — you may need to contact Microsoft support or use a password reset disk if you created one before you forgot your password.

On Mac, if you set up a recovery email or phone number in System Settings beforehand, you can restart your Mac and click "Forgot password?" on the login screen. If you did not set up recovery information, you will need to restart in Recovery Mode (hold Command + R while starting up) and use your Apple ID to reset your password.

Why you might want to change your password regularly

Changing your password every few months reduces the window of time that a stolen or guessed password can be used to access your account. If you use the same password on multiple websites and one of those sites gets hacked, changing your computer password means an attacker cannot use that leaked password to log into your machine.

You should change your password when ready if you think someone else knows it, if you used it on a website that was breached, or if you shared it with someone who no longer needs access. For routine security, changing it once or twice a year is usually enough for a home computer that only you use.

Changing your password on a work or school computer

If your computer is managed by an employer or school, the password change process may be different. Some organizations require you to change your password through a separate login portal rather than through Windows or Mac settings. Check with your IT department or help desk before trying the steps above — they may have locked down the standard password change method.

Work computers often have password rules that are stricter than home computers, such as requiring 14 characters or forbidding any password you have used in the past year. Your IT department can tell you what rules explore and whether you need to change your password on a schedule.

Frequently Asked Questions

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

No. On Windows, the change takes effect when ready, and you can keep working. On Mac, the change takes effect the next time you log in, but you do not need to restart — you can log out and log back in whenever you are ready.

What if I change my password but still cannot log in?

The most common reason is a typo in the new password during the change process. Restart your computer and try logging in again, paying close attention to uppercase and lowercase letters. If that does not work, try your old password — the change may not have gone through if there was an error.

Can I change my password from the login screen?

On Mac, yes — click "Forgot password?" on the login screen if you set up recovery information beforehand. On Windows, you cannot change your password from the login screen unless you use a Microsoft account and have internet access to reset it through Microsoft's website.

Will changing my password log me out of other devices?

On Windows and Mac, changing your local password does not affect other devices. If you use a Microsoft account on Windows or an Apple ID on Mac, changing your password will log you out of other devices using that account, and you will need to log back in with your new password.

Is it safe to use the same password on my computer and my email?

No. If someone guesses or steals your email password, they can use the password reset feature on any website to take over your accounts. Keep your email password separate and unique, and use different passwords for your computer and your important online accounts.
