The fastest way depends on your device type

Changing your lock screen password is different on Windows, Mac, and Chromebook — each has its own path through Settings. On Windows, you go to Settings > Accounts > Sign-in options. On Mac, it's System Settings > General > Login Items, then your Apple ID settings. On Chromebook, you change your Google Account password, which automatically updates your lock screen. The process takes two to five minutes on any device, and you'll need your current password to start.

If you've forgotten your current password entirely, the steps are longer — you'll need recovery options like a backup email or phone number. That's covered in the FAQ section below.

Key Takeaways

  • Windows users change their password in Settings > Accounts > Sign-in options, and can choose between a PIN, password, or Windows Hello biometric option.
  • Mac users go to System Settings > General > Login Items, then update their Apple ID password through their account settings.
  • Chromebook users change their Google Account password, which automatically secures their lock screen without a separate step.
  • You need your current password to make any change, unless you use a recovery email or phone number if you've forgotten it.
  • After you change your password, you'll use the new one the next time you lock and unlock your device.

Changing your password on Windows 10 and 11

Open Settings by pressing the Windows key and typing "Settings," then select it. Go to Accounts on the left sidebar, then click Sign-in options. Under the "Password" section, click Change. Windows will ask you to enter your current password first — type it and click Next.

Type your new password twice to confirm it matches, then add a password hint if you want one (this hint will be visible to anyone at your lock screen, so don't make it too obvious). Click Next, then Finish. Your new password takes effect the next time you lock your device or restart.

If you prefer not to use a password, Windows also lets you set up a PIN (a shorter numeric code) or Windows Hello (facial recognition or fingerprint). Both are found in the same Sign-in options menu, and you can have more than one method active at once.

Changing your password on Mac

Click the Apple menu in the top-left corner and select System Settings. Click General in the sidebar, then Login Items. You'll see your user account listed — click the lock icon next to it to unlock the settings (you'll need to enter your current password).

Once unlocked, look for your Apple ID section and click the button to change your password. Mac will prompt you to enter your current password, then your new password twice. After you confirm, the change takes effect immediately — you'll use your new password the next time you lock your Mac or it goes to sleep.

If you use iCloud on your Mac, changing your Apple ID password here also changes it across all your Apple devices. If you only want to change the password for unlocking your Mac (not your Apple ID), you can do that separately in the same menu — look for "Change password" under your user account details.

Changing your password on Chromebook

On a Chromebook, your lock screen password is tied to your Google Account, so you change it through Google's website rather than through your device settings. Open a web browser and go to myaccount.google.com, then sign in with your current Google Account password.

Click Security in the left sidebar, then scroll down to "How you sign in to Google" and click Password. Google will ask you to enter your current password again, then type your new password twice. Click Change Password to confirm. The next time you lock your Chromebook, you'll use your new Google Account password to unlock it.

If you're signed into multiple Google Accounts on your Chromebook, changing your password only affects the account you changed it for. Other accounts keep their old passwords until you change them separately.

What to do if you've forgotten your current password

If you can't remember your current password, you'll need to use a recovery method. On Windows, click "I forgot my password" on the lock screen — Windows will ask you to answer security questions you set up earlier, or send a code to your backup email or phone number. Once you verify your identity, you can set a new password.

On Mac, restart your device and hold Command + Q during startup to enter Recovery Mode. Click your user account, then click "Reset Password." You'll need to answer your security questions or use your Apple ID to verify your identity. On Chromebook, go to the Google Account recovery page (accounts.google.com/signin/recovery) and follow the prompts to verify your identity using a recovery email or phone number.

All three methods require that you set up recovery options beforehand — a backup email, phone number, or security questions. If you haven't set any of these up, you may need to contact support for your device type to regain access.

Keeping your new password secure

Once you've changed your password, write it down somewhere safe — a password manager like Bitwarden, 1Password, or the built-in password managers in Windows and Mac. Don't use the same password across multiple devices or accounts, and avoid passwords that contain your name, birthday, or other information someone could guess.

If you think someone else knows your password, change it again right away. On any device, you can also check your recent sign-in activity — Windows shows this in Settings > Accounts > Sign-in options, Mac shows it in System Settings > General > Login Items, and Google shows it at myaccount.google.com under Security > Your devices.

Frequently Asked Questions

Can I use the same password on multiple devices?

You can, but it's not recommended. If someone learns that password, they can access all your devices. Most people use a password manager to keep different passwords for each device and account, so they only have to remember one master password.

What happens if I change my password while I'm signed in?

On Windows and Mac, you stay signed in — the new password only takes effect when you lock and unlock your device next. On Chromebook, you may be signed out of some apps and services, and you'll need to sign back in with your new Google Account password.

Can I change my lock screen password without knowing my current one?

No, you need your current password to change it. If you've forgotten it, use your device's password recovery option (security questions, backup email, or phone number). If you haven't set up recovery options, you'll need to contact device support.

Does changing my lock screen password change my email password too?

On Windows, no — your lock screen password and email password are separate. On Mac and Chromebook, changing your Apple ID or Google Account password does change your email password, since both are tied to the same account.

How often should I change my lock screen password?

Most security experts recommend changing it only if you think someone knows it, or if you use the same password across multiple accounts. Changing it frequently doesn't add much security if the password is already strong and unique.
