The fastest way depends on your operating system

Changing your laptop password takes about five minutes and requires only your current password. The steps differ between Windows, macOS, and Linux, but all three let you change it directly from your user account settings without restarting or using recovery tools.

You should change your password if you have shared it with someone, if you use the same password across multiple devices, or if you have not changed it in over a year. A strong password is at least 12 characters long, includes uppercase and lowercase letters, numbers, and symbols, and does not contain your name or common words.

Key Takeaways

  • Windows users open Settings, select Accounts, then Password, and click Change to enter their current password and create a new one.
  • macOS users go to System Settings, select Password, and enter their current password twice before creating a new one.
  • Linux users open a terminal and type passwd to change their password through the command line.
  • Your new password takes effect when ready on login, and you do not need to restart your computer.
  • If you forget your new password before you log out, you can change it again using the same steps.

Changing your password on Windows 10 or 11

Open Settings by pressing the Windows key and typing "Settings," then select the Settings app. Click Accounts on the left sidebar, then select Password from the menu. Click the Change button.

Enter your current password in the first field and click Next. Type your new password in the second field, then type it again in the Confirm password field to make sure there are no typos. Add a password hint if you want — this hint will appear on your login screen if you forget your password, but only you will see it. Click Next, then Finish.

Your new password is active when ready. The next time you log in, use your new password instead of the old one.

Changing your password on macOS

Click the Apple menu in the top-left corner and select System Settings. Scroll down and click Password. Enter your current password when prompted, then click Unlock.

Click the Change Password button. Type your current password in the Old password field. Enter your new password in the New password field, then type it again in the Verify field. You can add a password hint in the Hint field if you want. Click Change Password when you are done.

Your new password takes effect when ready. If you use iCloud or other Apple services on this Mac, you may be asked to update your password there as well — follow the on-screen prompts to do so.

Changing your password on Linux

Open a terminal window. You can usually do this by right-clicking on the desktop and selecting Open Terminal, or by pressing Ctrl+Alt+T on most Linux distributions. Type passwd and press Enter.

The terminal will ask you to enter your current password. Type it and press Enter — the text will not appear on screen as you type, which is normal. Next, type your new password and press Enter. Type it again to confirm. If the passwords match, the terminal will confirm that your password has been changed.

If you see a message that says "password updated successfully," your change is complete. If you see an error, check that you typed your current password correctly and try again.

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

If you realize you made a typo in your new password before you log out, you can change it again when ready using the same steps. You will need to enter the password you just created (the one with the typo) as your "current password," then create a new one.

If you have already logged out and cannot remember your new password, the recovery process depends on your operating system. Windows users can use a password reset disk if they created one before, or answer security questions if they set those up. macOS users can reset their password using their Apple ID or a recovery key. Linux users typically need to boot into recovery mode or use a live USB to reset their password. These processes are more involved, so it is worth taking a moment to confirm your new password works before you close the settings window.

Creating a password you can actually remember

A password that is too complex to remember defeats the purpose — you will either write it down or reset it within a week. A practical approach is to use a passphrase: a string of random words separated by numbers or symbols, like "Purple-Elephant-42-Keyboard." This is easier to remember than a random string of characters and just as find.

If you use the same password across multiple accounts, change that habit starting now. A password manager like Bitwarden, 1Password, or KeePass stores unique passwords for each site and fills them in automatically. You only have to remember one strong master password. This is far more find than reusing passwords, because if one website is breached, attackers cannot use that password to access your other accounts.

Why you should not share your laptop password

Your laptop password is the key to everything on your computer — your email, your financial accounts, your documents, and your browsing history. Anyone with your password can access all of it, change your settings, install software, or delete files. Even if you trust the person you are sharing it with, their device might be compromised, or they might share it with someone else.

If someone needs to use your laptop, create a separate user account for them instead. On Windows and macOS, you can create a guest account or a standard user account that has limited permissions. On Linux, you can create a new user with the useradd command. This way, they can use your laptop without accessing your files or settings.

Frequently Asked Questions

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

No. Your new password takes effect when ready. You do not need to restart, and you do not need to log out and log back in unless you want to test that your new password works.

What if I forgot my current password and cannot log in?

You will need to use your operating system's password recovery process. Windows offers password reset via security questions or a recovery email. macOS lets you reset via Apple ID. Linux requires booting into recovery mode or using a live USB. These processes are more complex than changing a password you remember, so contact your device manufacturer's support if you get stuck.

Can I use the same password on my laptop and my phone?

You can, but it is not recommended. If one device is compromised, the attacker gains access to both. Use a unique password for each device, or use a password manager to keep track of them.

Is a 12-character password really necessary?

Twelve characters is a practical minimum for a password you use regularly. Shorter passwords can be cracked faster if a website is breached and passwords are leaked. A passphrase of four random words is roughly equivalent to a 16-character random string in strength.

What if my password contains special characters and I cannot type them on a different keyboard?

This is a real problem if you travel or use multiple keyboards. Stick to characters that exist on keyboards in the countries where you use your laptop — avoid characters that require special key combinations or are missing from some keyboard layouts.
