The fastest way depends on whether you use Windows or Mac

On Windows, you open Settings, go to Accounts, then select "Password" and click "Change." On Mac, you open System Settings, choose "General," then "Login Items & Extensions," scroll down to find your user account, and click the lock icon to make changes. Both take about two minutes if you remember your current password. If you do not remember it, the process is longer and depends on whether you set up a recovery email or phone number.

The reason to change your password regularly is straightforward: the longer a password stays the same, the more places it may have been typed, photographed, or seen over someone's shoulder. A password change does not erase those old exposures, but it stops anyone using an old password from getting in.

Key Takeaways

  • Windows users go to Settings > Accounts > Password > Change to update their login password in about two minutes.
  • Mac users go to System Settings > General > Login Items & Extensions, find their account, click the lock, and change the password from there.
  • You will need to enter your current password before you can set a new one, so have it ready.
  • A strong new password should be at least 12 characters long and mix uppercase letters, lowercase letters, numbers, and symbols.
  • If you forget your current password, Windows and Mac both offer recovery options, but they require you to have set up a backup email or phone number beforehand.

Step-by-step for Windows 10 and Windows 11

Open the Start menu and type "Settings" into the search box. Click the Settings app when it appears. On the left side, click "Accounts." In the middle of the screen, you will see several options; click "Password."

Click the button that says "Change." Windows will ask you to enter your current password. Type it in and click "Next." Now you will see two boxes: one for your new password and one to confirm it. Type your new password in both boxes — make sure they match exactly, because Windows will reject them if they do not. Click "Next," then "Finish." You are done. The next time you log in, use the new password.

Step-by-step for Mac

Click the Apple menu in the top-left corner of your screen. Select "System Settings" (on newer Macs) or "System Preferences" (on older ones). On the left sidebar, click "General." Scroll down until you see "Login Items & Extensions" — click that.

You will see a list of user accounts. Find your own name in that list. To the right of your account name, you will see a lock icon. Click it. Mac will ask you to enter your current password to unlock the settings. Type it in and click "Unlock." Now click the "Password" tab at the top. Enter your current password in the first box, then type your new password in the second and third boxes. Click "Change Password" and you are finished.

What makes a password actually hard to guess

A strong password is long first, then mixed. Aim for at least 12 characters. Use uppercase letters, lowercase letters, numbers, and symbols — things like ! @ # $ % ^ & *. A password like "BlueSky2024!" is stronger than "password123" even though both have numbers, because the first one is longer and uses uppercase and symbols.

Avoid passwords based on your name, your birth date, your pet's name, or words you can find in a dictionary. These are the first things someone will try if they want to break in. A random mix like "Tr0pic@lMango#92" is harder to crack than something meaningful to you, because there is no pattern to guess.

Do not reuse the same password across multiple accounts. If one website gets hacked and your password is stolen, someone could use that same password to try to log into your laptop, your email, your bank, and everywhere else. A password manager like Bitwarden, 1Password, or KeePass can store different strong passwords for each account so you only have to remember one master password.

What to do if you forget your current password

On Windows, restart your laptop and look at the login screen. Below the password box, you will see a link that says "I forgot my password." Click it. Windows will ask you security questions or send a code to a recovery email address or phone number — but only if you set one up before you forgot your password. If you did not, you will need to contact Microsoft support or use a Windows installation disc to reset it, which is much slower.

On Mac, restart and hold down Command + Q when you see the login screen. This opens the reset password utility. Mac will ask you to answer security questions or verify your identity using your Apple ID. Again, this only works if you set up these recovery options beforehand. If you did not, you will need to use your Mac's recovery mode, which requires more technical steps.

The lesson here is straightforward: set up a recovery email and phone number now, before you need them. You can do this in Windows Settings under "Accounts" and on Mac under "System Settings" > "General." It takes five minutes and saves you hours of trouble later.

Why your laptop might not let you change your password

If you are on a work laptop, your company may have locked down password changes. You might see a message saying "Your password is managed by your organization" or "You do not have permission to change this." In that case, contact your IT department or help desk — they control the password policy and can either change it for you or walk you through the company's process.

If you are on your own laptop and still cannot change your password, make sure you are logged in with an account that has administrator rights. On Windows, right-click Settings and choose "Run as administrator." On Mac, the account you are using must be an admin account. If you are not sure, go to Accounts settings and look for a label that says "Admin" next to your name.

Protecting your new password once you have set it

Once you have changed your password, do not type it in front of other people. Do not write it down on a sticky note and leave it on your desk. Do not text it to yourself or email it to yourself — if your email gets hacked, your laptop password goes with it.

If you use the same laptop at home and at work, be aware that your workplace may have the right to monitor what you do on it, even if you use it at home. Check your company handbook or ask your IT department what they can see. This is not about your password — it is about understanding what privacy you actually have on a device your employer owns or controls.

Frequently Asked Questions

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

No. The change takes effect when ready. The next time you log out and log back in, you will use the new password. You can keep working without restarting.

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

On Windows, use the "I forgot my password" link on the login screen if you set up a recovery email or phone. On Mac, use the reset password utility. If you did not set up recovery options, you will need to contact support or use recovery mode, which is slower.

Can I change my password from a different device?

No. Your laptop password is stored on your laptop itself. You have to change it by logging into that laptop. You cannot change it from your phone or another computer.

Will changing my password log me out of everything?

No. You stay logged in on your laptop. You will only need to use the new password the next time you log in after restarting or locking your screen.

Is it safe to use a password manager to store my laptop password?

Yes, if the password manager itself is strong. Tools like Bitwarden and 1Password encrypt your passwords so that even the company running the service cannot read them. The trade-off is that if you forget your master password, you lose access to all your stored passwords, so write it down and keep it somewhere safe offline.
