The fastest way depends on your operating system

On Windows 10 or 11, press Ctrl + Alt + Delete at the login screen or from your desktop, then select "Change a password" from the menu that appears. Type your current password, then your new password 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, select your account, and click "Change Password".

Both methods take about two minutes. You do not need to restart your computer afterward, though some programs may ask you to sign in again the next time you open them. If you have forgotten your current password, the process is different — you will need to use a recovery method instead of changing it directly.

Key Takeaways

  • Windows users press Ctrl + Alt + Delete and select "Change a password" from the menu.
  • Mac users open System Settings, navigate to Users & Groups, and click "Change Password" after unlocking the preferences.
  • You will need to enter your current password before creating a new one on both systems.
  • Your new password should be at least 8 characters long and include a mix of uppercase, lowercase, numbers, and symbols for better security.
  • Programs and cloud services may ask you to sign in again after you change your password.

Changing your password on Windows 10 and 11

Start at your login screen or your desktop. Press Ctrl + Alt + Delete together. A menu will appear with several options. Click "Change a password" — it is usually the third option on the list.

A dialog box will open asking for three passwords. In the first field, type the password you use right now. In the second field, type your new password. In the third field, type that same new password again to confirm it. Windows will check that both new passwords match before letting you proceed. Click the arrow or press Enter to finish.

If you see a message saying the password does not meet requirements, Windows is telling you the new password is too short or does not have enough variety in character types. Most systems require at least 8 characters and a mix of uppercase letters, lowercase letters, numbers, and symbols like ! or @.

Changing your password on 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). Look for "General" in the sidebar on the left, then click it. You should see a section labeled "Users & Groups" — click that.

You will see a list of user accounts on your Mac. Click your own account name to select it. Below the list, you will see a "Change Password" button, but it may be grayed out. If it is, click the lock icon at the bottom left of the window, then enter your current password when prompted. This unlocks the settings so you can make changes.

Once the lock is open, click "Change Password" again. A window will ask for your current password, then your new password twice. Type carefully — passwords are case-sensitive, meaning Capital and lowercase letters are treated as different. Click "Change Password" to save your new password.

What to do if you see an error message

If Windows or Mac tells you the password is too weak, it means your new password does not meet the system's security rules. Add more characters, mix in uppercase and lowercase letters, or include a number or symbol. A strong password might look like "BlueSky2024!" instead of just "bluesky".

If you see a message saying the two new passwords do not match, you typed them differently. This is a safety feature — the system wants to make sure you did not accidentally mistype your new password. Go back and type both new passwords exactly the same way, paying attention to capital letters and special characters.

If the system says your current password is wrong, you may have caps lock on, or you may be misremembering it. Check that caps lock is off by looking at the caps lock key light on your keyboard. If you are certain your current password is correct and the system still rejects it, you may need to use your password recovery method instead.

What happens after you change your password

Your new password takes effect when ready. You do not need to restart your computer. However, any programs or websites where you have saved your password may ask you to sign in again the next time you open them. This includes email clients like Outlook, cloud storage services like OneDrive or iCloud, and browsers that have saved your login information.

If you use your Microsoft account to sign in to Windows, or your Apple ID to sign in to Mac, changing your computer password does not automatically change your account password online. You will still be able to sign into your Microsoft or Apple account with your old password on other devices. If you want to change that account password too, you will need to do it through the company's website.

Write your new password somewhere safe if you need to remember it. A password manager like Bitwarden or 1Password can store it securely so you do not have to type it from memory every time.

Creating a password that is hard to guess

A strong password is long and uses different types of characters. Aim for at least 12 characters if your system allows it. Mix uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and symbols (!@#$%^&*). Avoid using your name, your birth year, or common words that appear in the dictionary.

A weak password looks like "password123" or "qwerty". A stronger one looks like "Tr0pical!Sunset#42" or "GreenMountain$2024". The longer and more random it is, the harder it is for someone to guess or crack it with a computer program.

Do not use the same password on multiple devices or websites. If one service gets hacked, someone could use that password to break into your other accounts. If you have trouble remembering different passwords, a password manager handles that for you.

If you have forgotten your current password

You cannot use the "Change a password" method if you do not remember your current password. Instead, you will need to use your recovery options. On Windows, click "I forgot my password" at the login screen. You will be asked to verify your identity using a recovery email, a phone number, or security questions you set up earlier.

On Mac, restart your computer and hold Command + Q at the login screen to open the recovery menu. Select "Reset Password" and follow the prompts. You may be asked to use your Apple ID or a recovery key to prove your identity.

If you do not have access to your recovery email, phone, or Apple ID, you may need to contact Microsoft or Apple support, or take your computer to a repair shop. This is why setting up recovery options when you first set up your computer is important.

Frequently Asked Questions

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

No. Your new password takes effect right away. You can keep using your computer normally. Some programs may ask you to sign in again the next time you open them, but that is not the same as restarting.

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

Use your recovery method — the same one you would use if you had forgotten any password. On Windows, click "I forgot my password" at the login screen. On Mac, restart and hold Command + Q to access recovery options. You will need to verify your identity with a recovery email, phone number, or security questions.

Will changing my computer password change my email or social media passwords?

No. Your computer password and your online account passwords are separate. Changing one does not change the others. If you want to change your Microsoft, Apple, Gmail, or social media passwords, you must do that on each service's website separately.

Can I use special characters like @ or # in my password?

Yes. Most systems encourage special characters because they make passwords stronger. Symbols like !, @, #, $, %, and ^ are all allowed. Avoid only the characters your system specifically tells you are not allowed.

How often should I change my password?

There is no fixed rule. Change it if you think someone may have seen it, if you use the same password on multiple devices, or if you have not changed it in over a year. If your password is unique and strong, changing it less often is fine.
