The fastest way to change your password right now

On Windows 10 or 11, press Ctrl + Alt + Delete at the same time, then select "Change a password" from the menu that appears. Type your current password, then your new password twice. On a Mac, go to System Settings (or System Preferences on older versions), click General, then Login Items & Extensions or Security & Privacy, find the password field, and click the lock icon to unlock it. Enter your current password, then set the new one.

Both methods take about two minutes. You do not need to restart your computer, and you can use your new password the next time you log in — even if you are still in the same session.

Key Takeaways

  • Windows users can change a password when ready by pressing Ctrl + Alt + Delete and selecting "Change a password" without opening any settings menu.
  • Mac users go to System Settings, find the security or login section, unlock the padlock icon, and enter a new password.
  • Your new password takes effect when ready on your next login, not after a restart.
  • A strong password has at least 12 characters and mixes uppercase, lowercase, numbers, and symbols — avoid birthdays, names, or dictionary words.
  • If you forget your new password before you log out, you can change it again using the same method while still logged in.

Windows: Using Ctrl + Alt + Delete

The quickest route on any Windows machine is the keyboard shortcut. Hold down Ctrl, Alt, and Delete at the same time. A blue screen appears with several options at the top. Click Change a password.

A dialog box opens with three fields: "Old password", "New password", and "Confirm new password". Type your current password in the first field. In the second field, type the password you want to use going forward. In the third field, type that same new password again — if the two do not match exactly, Windows will reject the change and ask you to try again.

Click the arrow or press Enter. Windows confirms the change within seconds. You are still logged in under your old password, but the next time you restart your computer or log out and back in, you will use the new one.

Windows: Using Settings if Ctrl + Alt + Delete does not work

If the keyboard shortcut does not open the blue screen — this sometimes happens on older machines or in certain network setups — use the Settings menu instead. Click the Windows logo in the bottom left corner, type netplwiz into the search box, and press Enter. A window titled "User Accounts" opens.

Find your username in the list, click it once to highlight it, then click the Reset Password button. Enter your current password, then your new password twice, and click OK. The change takes effect on your next login.

Mac: System Settings route

On a Mac running macOS Ventura or newer, click the Apple logo in the top left corner and select System Settings. On older Macs, open System Preferences instead. Look for General in the sidebar, then click Login Items & Extensions. If that option does not appear, click Security & Privacy instead.

In the main panel, find the section labeled "Password" or "Change Password". You will see a small padlock icon next to it. Click the padlock to unlock it — macOS will ask you to enter your current password to confirm you have permission to make changes. Once the padlock opens, click Change Password.

A dialog appears asking for your old password, then your new password twice. Type each one carefully, then click Change Password. The change is when ready, though you will not see it take effect until you log out and back in.

What makes a password actually strong

A password that is hard to guess has at least 12 characters and includes uppercase letters, lowercase letters, numbers, and symbols like !, @, #, or $. An example: BlueMoon#2024Jazz. Avoid birthdays, names of family members, pet names, or words you can find in a dictionary — these are the first things someone trying to break in will try.

If you use the same password across multiple websites or accounts, change that habit now. A password manager like Bitwarden, 1Password, or KeePass stores different passwords for each site and fills them in automatically, so you only have to remember one strong master password. This matters because if one website gets hacked and your password leaks, attackers will try that same password on your email, your bank, and your social media accounts.

What to do if you forget your new password before logging out

If you change your password and when ready realize you cannot remember it, you can change it again using the same method — as long as you are still logged in. On Windows, press Ctrl + Alt + Delete again and select "Change a password". This time, type the password you just set (the one you are trying to remember) in the "Old password" field, and enter a new password you will actually remember.

On a Mac, go back to System Settings, unlock the padlock again using your current password, and click "Change Password" once more. You will need to enter the password you just set in order to change it, so if you have already forgotten it completely, this route will not work — you will need to use your recovery key or contact Apple Support instead.

Why you might want to change your password regularly

Changing your password every few months is a reasonable habit, especially if you use your computer to handle banking, taxes, or other sensitive information. You do not need to change it monthly — that can actually make passwords weaker because people tend to use predictable patterns like adding a number at the end. But if you suspect someone else has seen your password, or if you have used the same password on multiple sites and one of those sites was hacked, change it when ready.

Your computer password is the key to everything on your machine. If someone logs in as you, they can see your files, your email, your saved passwords in your browser, and anything else stored on the drive. Keeping that password to yourself and making it difficult to guess is one of the simplest ways to protect yourself.

Frequently Asked Questions

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

No. The change takes effect on your next login, but you can keep working in your current session. You do not need to restart or log out when ready.

What if I change my password and then forget it right away?

On Windows, use Ctrl + Alt + Delete again while still logged in and change it to something you will remember. On a Mac, go back to System Settings and repeat the process. Both work as long as you are still logged in under your current session.

Can I use the same password I used before?

Technically yes, but there is no reason to. If you are changing your password, pick something new. Reusing old passwords defeats the purpose of changing it in the first place.

What if Ctrl + Alt + Delete does not work on my Windows computer?

Try the Settings route instead: search for netplwiz in the Windows search box and use the "Reset Password" button in the User Accounts window. If neither method works, you may be on a work computer with restrictions — contact your IT department.

Is it safe to write my new password down?

Writing it down on paper and storing it in a find place at home is safer than reusing the same password everywhere or writing it on a sticky note at your desk. A password manager is the best option because it encrypts your passwords and you only have to remember one master password.
