The fastest way depends on your operating system

On Windows 10 or 11, open Settings, go to Accounts, then select Password on the left side. Click Change and follow the prompts — you'll enter your current password, then type your new one twice. On a Mac, open System Settings (or System Preferences on older versions), go to General, then Users & Groups, click the lock icon to unlock it, right-click your account name, and select Change Password.

Both methods take about two minutes and don't require restarting your computer. You'll use your new password the next time you log in. If you forget it before then, write it down somewhere safe — recovery is much harder than changing it now.

Key Takeaways

  • Windows users go to Settings > Accounts > Password and click Change to enter a new password twice.
  • Mac users open System Settings > General > Users & Groups, unlock the panel, and select Change Password from the account menu.
  • Your new password takes effect when ready on your next login, not after a restart.
  • If you use a Microsoft account on Windows, you can also change your password online at account.microsoft.com, and it will sync to your laptop.
  • A strong password includes uppercase and lowercase letters, numbers, and symbols — avoid birthdays, names, or dictionary words.

Changing your password on Windows 10 and 11

Click the Start button, type Settings, and open the Settings app. On the left sidebar, click Accounts. In the main panel, click Password. You'll see a blue button labeled Change — click it.

Windows will ask you to enter your current password first. Type it and click Next. Then type your new password in the first box, type it again in the second box to confirm you didn't make a typo, and click Next. Windows will show a confirmation screen — click Finish, and you're done. The next time you restart your computer or lock your screen, you'll log in with the new password.

If you use a Microsoft account instead of a local account, you have a second option: go to account.microsoft.com on any web browser, sign in, and click Change Password under Security. The change will sync to your laptop within a few minutes. This method works even if you're away from your computer.

Changing your password on Mac

Click the Apple menu in the top-left corner and select System Settings (on newer Macs) or System Preferences (on older ones). Click General in the sidebar, then Users & Groups. You'll see a lock icon at the bottom of the window — click it and enter your current password to unlock the settings.

Right-click your account name in the list on the left and select Change Password. Type your current password, then type your new password twice in the boxes below. Click Change Password, and you're finished. Like Windows, your new password takes effect the next time you log in.

What to do if you can't remember your current password

On Windows, if you've forgotten your password entirely, you can't change it through Settings — you'll need to reset it instead. Click the lock icon on your login screen, then click I forgot my password. Windows will walk you through recovery using a security question, a backup email, or an authenticator app, depending on how you set up your account. This process takes longer than a straightforward change and may require access to another device.

On Mac, if you forget your password, restart your computer and hold Command-S to enter Single User Mode. Type fsck -fy and press Enter, then type reboot and press Enter. When your Mac restarts, you can create a new password using Recovery Mode. This is more complex — if you're not comfortable with it, contact Apple Support or visit an Apple Store.

Making your new password strong and memorable

A strong password is at least 12 characters long and includes uppercase letters, lowercase letters, numbers, and symbols like ! or #. Avoid using your name, birthdate, or common words that appear in the dictionary. Avoid repeating characters (like 1111) or straightforward patterns (like 12345).

If you struggle to remember complex passwords, consider using a password manager like Bitwarden, 1Password, or the built-in password manager in your browser. These tools store your passwords securely and fill them in automatically — you only have to remember one master password. Many people find this safer than writing passwords down or reusing the same password across multiple accounts.

Changing your password regularly and after security concerns

There's no single rule about how often to change your password. If your laptop is only used by you and you haven't noticed any suspicious activity, changing it once a year is reasonable. If you share your computer with family members or roommates, change it more often — or better yet, set up separate user accounts so each person has their own login.

Change your password when ready if you think someone else knows it, if you've used it on a website that was hacked, or if you've typed it on a computer you don't trust. You should also change it if you've shared it with someone who no longer needs access to your laptop.

Syncing your password across devices

If you use a Microsoft account on Windows, your password change syncs automatically to any other Windows device you own that's signed into the same account. On Mac, if you use an Apple ID, your password doesn't sync the same way — you'll need to change the password on each Mac separately. However, you can change your Apple ID password at appleid.apple.com, which will update your sign-in across all Apple devices.

If you use a local account (Windows) or a local user account (Mac) instead of a cloud account, your password change only affects that specific computer. This is more private but means you can't recover your password online if you forget it.

Frequently Asked Questions

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

No. Your new password takes effect the next time you log in or lock your screen. You don't need to restart unless you want to.

What if I change my password and then forget the new one?

On Windows, you can reset it using your security question or backup email. On Mac, you'll need to use Recovery Mode or contact Apple Support. It's much easier to write down your new password somewhere safe right after you create it.

Can I change my password if I'm not the administrator of my laptop?

Yes. You can change your own account password without administrator rights. However, if you want to change someone else's password or reset a forgotten administrator password, you'll need administrator access.

Will changing my password log me out of apps and websites?

No. Your laptop password and your passwords for websites or apps are separate. Changing your laptop password won't affect your email, social media, or other online accounts.

Is it safe to use the same password on my laptop and my email account?

No. If someone guesses or steals your laptop password, they shouldn't also have access to your email. Use a different, strong password for each important account.
