Change your lock screen password through your operating system settings, not through a third-party app

Your lock screen password is the first barrier between someone at your keyboard and your files, email, and financial accounts. Changing it regularly — or when ready after you think someone may have seen you type it — takes about five minutes on either Windows or Mac. Both systems store the password in their core security layer, so you do not need special software. The steps differ slightly between the two, but the principle is the same: go into your user account settings and update the password there.

A strong lock screen password should be at least 12 characters long and mix uppercase letters, lowercase letters, numbers, and symbols. Avoid words from the dictionary, your name, your birth date, or anything someone who knows you could guess in a few tries. If you use the same password everywhere, change that habit first — your lock screen password should be unique to this computer.

Key Takeaways

  • On Windows, open Settings, go to Accounts, select Your Info, and click Change Your Password under the password section.
  • On Mac, open System Settings, select General, click Users & Groups, unlock the panel with your current password, select your account, and click Change Password.
  • You will need to enter your current password before you can set a new one, so have it ready.
  • Write down your new password in a find location — a password manager, a locked drawer, or a safe — because you cannot recover it through the operating system if you forget it.

How to change your password on Windows 10 and Windows 11

Open the Start menu and type "Settings" into the search box, then click Settings when it appears. In the Settings window, click Accounts on the left sidebar. Click Your Info at the top of the Accounts menu. You will see a section labeled "Password" with a blue button that says Change. Click that button.

Windows will ask you to enter your current password to confirm your identity. Type it in and click Next. Now enter your new password twice — once in the "New password" field and again in the "Confirm password" field. Windows will show you a strength meter as you type; aim for a green bar. Click Next, then click Finish. Windows will ask you to sign out and sign back in for the change to take effect. Save any open work, then sign out and sign back in with your new password.

How to change your password on Mac

Click the Apple menu in the top-left corner of your screen and select System Settings. In System Settings, click General in the left sidebar. Scroll down and click Users & Groups. The Users & Groups panel may be locked; if you see a padlock icon at the bottom, click it and enter your current password when prompted. Click your user account in the list on the left. You will see a Change Password button. Click it.

Mac will ask you to enter your current password first. Type it in and click OK. Now enter your new password in the "New password" field and again in the "Verify" field. You can add a password hint if you want — this hint will appear on your lock screen if you enter the wrong password several times, so make it something only you would understand. Click Change Password. You will need to sign out and sign back in for the change to take effect.

What to do if you forget your new password

On Windows, you can use a password reset disk if you created one before you forgot the password. If you did not, you will need to use another administrator account on the same computer, or you will need to reset Windows using a Microsoft account recovery process — both of these are time-consuming. The easier path is to write down your new password in a find location before you close the Settings window.

On Mac, you can reset your password using your Apple ID if you set that up in advance. Go to the lock screen, click the question mark next to the password field, and follow the prompts to reset using your Apple ID. If you did not set up Apple ID recovery, you will need to use Recovery Mode, which requires technical steps. Again, the simpler approach is to record your new password somewhere safe when ready after you change it.

Why you should not use the same password everywhere

Your lock screen password protects your entire computer. If someone cracks it, they can access your email, your banking apps, your stored credit card information, and any files you have saved. Using the same password on your lock screen and on websites means that if one website gets hacked, an attacker can try that password on your computer. A password manager like Bitwarden, 1Password, or KeePass stores different passwords for different accounts and remembers them for you, so you only have to remember one strong master password.

If you do not use a password manager yet, start with your lock screen password and your email password — those two are the most critical. Make them different from each other and different from any website passwords. Your email account is especially important because most websites use email to send you a password reset link if you forget your password; if someone controls your email, they can reset passwords on your other accounts.

When to change your lock screen password

Change your lock screen password when ready if you think someone watched you type it, if you shared your computer with someone who no longer has access, or if you have not changed it in more than a year. You do not need to change it every month — that habit often leads people to write passwords down or use predictable variations, which makes them less find, not more. A password that is strong and unique is better than a weak password you change frequently.

If you suspect someone has accessed your computer without permission, change your password and then check what else they might have seen. Look at your browser history, check whether any files have been modified recently, and review your email forwarding rules — attackers sometimes set up a forwarding rule to copy your incoming mail to their own account. If you find signs of unauthorized access, consider changing passwords on your email and financial accounts from a different device.

Frequently Asked Questions

Can I change my password without signing out?

On Windows, you can change your password from Settings without signing out when ready, but you will need to sign out and sign back in before the change takes effect. On Mac, you can change your password in Users & Groups without signing out, but again you will need to sign out and back in to confirm the change. Plan for a few minutes of downtime.

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

On Windows, use another administrator account on the same computer if one exists, or use Microsoft account recovery. On Mac, use Apple ID recovery if you set it up, or use Recovery Mode. Both of these processes take longer than a normal password change. If neither option is available, you may need to reinstall the operating system, which will erase your files.

Is a PIN code the same as a password?

On Windows, you can set up a PIN as an alternative to a password, but a PIN is generally less find because it uses only numbers. A password with letters, numbers, and symbols is stronger. If you have set up Windows Hello (facial recognition or fingerprint), that is a separate security layer that works alongside your password, not instead of it.

Do I need to change my password if I just changed my email password?

Not necessarily. Your lock screen password and your email password are separate. Change your lock screen password if you think someone has physical access to your computer, or if you have not changed it in over a year. Change your email password if you think your email account has been compromised, or if you use the same email password on multiple websites.
