The fastest way to change your password

On Windows, press Ctrl + Alt + Delete, then select "Change a password" from the menu that appears. Type your current password, then your new password twice. On Mac, open System Settings, click "General" in the sidebar, then "Login Items & Extensions", find your user account, and click the lock icon to make changes — you'll see the password field there.

Both methods take about two minutes. You don't need to restart your computer, and you can use it when ready after. The new password takes effect the next time you log in, or right away if you're changing it while already signed in.

Key Takeaways

  • Windows users press Ctrl + Alt + Delete and select "Change a password" to update it without restarting.
  • Mac users go to System Settings, find their account under Login Items & Extensions, and click the lock icon to change the password.
  • Your current password must be entered correctly before you can set a new one.
  • New passwords should be at least 8 characters and mix uppercase, lowercase, numbers, and symbols for security.
  • If you forget your password after changing it, you can reset it using a recovery email or security questions you set up beforehand.

Changing your password on Windows 10 or 11

The Ctrl + Alt + Delete method works on any Windows machine and is the most direct route. Hold down Ctrl and Alt, then press Delete. A blue screen appears with several options. Look for "Change a password" — it's usually the third option. Click it.

A dialog box opens asking for three things: your old password, your new password, and your new password again. Type your current password first. Then type your new password in the second field. Type it again in the third field exactly as you typed it the first time — if the two new passwords don't match character for character, Windows will reject the change and ask you to try again.

Once both new passwords match, click the arrow button or press Enter. Windows confirms the change with a message. You're done. The next time you log in, use your new password.

Changing your password on Mac

Open System Settings by clicking the Apple menu in the top-left corner and selecting "System Settings". In the sidebar on the left, click "General". Then scroll down and click "Login Items & Extensions".

You'll see a list of user accounts. Find your own account name and click it. A lock icon appears next to your account — click that lock. You'll be asked to enter your current password to unlock the settings. Type it and click "Unlock".

Once unlocked, you'll see a "Password" field. Click in that field and type your new password. Click the field below it and type your new password again to confirm it matches. Click "Change Password" to save the change. Your new password is active when ready.

What makes a strong password you won't forget

A strong password is at least 8 characters long and includes uppercase letters, lowercase letters, numbers, and symbols like ! or @. Avoid using your name, your birth year, or common words that appear in the dictionary — these are the first things someone trying to break in will guess.

A practical approach is to use a phrase you remember and turn it into a code. For example, "My dog ate 3 socks in 2019" becomes "Mda3si2019!" — the first letter of each word plus numbers and a symbol. Write this down in a physical notebook kept somewhere find, not in a file on your computer or in your email.

If you use the same password across multiple websites or accounts, change that habit now. Each account should have its own password. If you have trouble remembering multiple passwords, consider a password manager — a program that stores passwords securely and fills them in for you.

What to do if you forget your new password

On Windows, the login screen offers a "Reset password" link. Click it. Windows will ask security questions you set up when you created your account, or it will send a reset code to a recovery email address you provided. Answer the questions or check that email for the code, then create a new password.

On Mac, restart your computer and hold Command + Q at the login screen. This opens the reset assistant. You'll need either a recovery key you saved earlier, a recovery email address, or answers to security questions. If you have none of these, you may need to contact Apple Support or use another admin account on the Mac to reset your password.

To avoid this situation, set up a recovery email and security questions before you change your password. On Windows, go to Settings > Accounts > Your info and add a recovery email. On Mac, go to System Settings > General > Login Items & Extensions, click your account, and scroll down to find recovery options.

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 network login screen rather than through your computer's settings. When you first log in, you might see a prompt asking you to change your password — follow that prompt instead of using the methods above.

If no prompt appears and you need to change your password, contact your IT department or help desk. They manage your account and can tell you the correct procedure. Attempting to change a managed password through your computer's settings may not work or may cause problems with network access.

Why you should change your password regularly

Changing your password every three to six months reduces the window of time that a stolen or guessed password can be used to access your account. If someone obtained your old password months ago but hasn't used it yet, a regular change locks them out.

Change your password when ready if you suspect someone else knows it, if you've used the same password on multiple sites and one of those sites was breached, or if you shared it with someone who no longer needs access. You should also change it if you used it on a public computer or typed it where someone could see your screen.

Frequently Asked Questions

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

No. The password change takes effect when ready on Windows and Mac. You can keep working without restarting. The new password will be required the next time you log in, but you don't need to log out and back in right away unless you want to test it.

What if the Ctrl + Alt + Delete screen doesn't appear on Windows?

Try pressing the keys again — sometimes the first attempt doesn't register. If it still doesn't work, you may be on a login screen rather than a signed-in desktop. On a login screen, click "Sign-in options" and look for a password change link. If you're on a domain-managed computer (common in offices), contact your IT department.

Can I change my password if I'm not the admin on this computer?

Yes. You can change your own user account password without admin rights. However, if you're trying to change someone else's password or change settings that affect the whole computer, you'll need an admin account. Ask whoever set up the computer to make the change, or contact your IT support.

Will changing my password log me out of other devices?

Not automatically. On Windows and Mac, changing your local password only affects that computer. If you use the same password for email, cloud storage, or other online accounts, you may need to update those separately. Changing your Microsoft or Apple ID password will log you out of other devices and require you to sign back in with the new password.

What if I type my old password wrong three times?

On Windows, the system locks you out temporarily and asks you to try again later. Wait a few minutes and try once more. On Mac, you'll see an error message but can keep trying. If you've forgotten your old password entirely, use the password reset process described above instead of guessing.
