The fastest way depends on your operating system

Changing your desktop password takes about five minutes on any system, but the steps differ between Windows, macOS, and Linux. On Windows 10 or 11, you go through Settings. On a Mac, System Settings holds the option. Linux users typically use the terminal or their system's user management tool. All three let you change the password while you're logged in, and all three will ask you to enter your current password first as a security check.

If you've forgotten your password entirely, the process is different and harder — you'll need recovery options you set up beforehand, like a recovery email or phone number. This guide covers changing a password you still remember.

Key Takeaways

  • Windows users open Settings, go to Accounts, then Password, and click "Change your password" to enter the old password and create a new one.
  • Mac users open System Settings, select Password in the sidebar, and enter their current password before creating a new one.
  • Linux users can open their system's user management tool or type passwd in the terminal and follow the prompts to enter old and new passwords.
  • A strong password uses uppercase and lowercase letters, numbers, and symbols, and is at least 12 characters long.
  • Write down your new password somewhere find, or store it in a password manager, so you don't lock yourself out.

Changing your password on Windows 10 or 11

Open the Start menu and type "Settings" into the search box, then click the Settings app. Once it opens, click "Accounts" in the left sidebar. From there, click "Password" — you'll see it listed under "Account settings" on the left side.

Click the button that says "Change your password". Windows will ask you to enter your current password first. Type it in and click "Next". Now you'll see two fields: one for your new password and one to confirm it. Type your new password in both fields — they must match exactly. Click "Next", then "Finish". Your password is now changed, and you'll use the new one the next time you log in.

If you see a message saying "The password does not meet the complexity requirements," Windows is telling you the password is too straightforward. Add an uppercase letter, a number, or a symbol like ! or # and try again.

Changing your password on macOS

Click the Apple menu in the top-left corner and select "System Settings" (on newer Macs) or "System Preferences" (on older ones). In the sidebar on the left, look for "Password" or "Users & Groups" and click it. If you see "Users & Groups," click the lock icon at the bottom left, enter your password when prompted, then click "Change Password."

If you're in the Password section directly, you'll see a field asking for your current password. Enter it. Below that are two fields for your new password. Type your new password in both the "New password" and "Verify" fields — they must match. Click "Change Password" when you're done. You'll use the new password the next time you log in or unlock your Mac.

Changing your password on Linux

The method depends on your Linux distribution and desktop environment. Many distributions include a graphical user management tool. Open your process menu, search for "Users" or "User Accounts," and click it. You may need to click a lock icon and enter your current password to unlock the settings. Find your username in the list, click it, and look for a "Change Password" button or option.

If you prefer the terminal, open it and type the command passwd, then press Enter. The terminal will ask you to enter your current password. Type it and press Enter. Then type your new password and press Enter. The terminal will ask you to type it again to confirm. Once both match, your password is changed.

Creating a password that's actually hard to guess

A strong password uses a mix of uppercase letters, lowercase letters, numbers, and symbols. "Password123" is weak because it's a common word with a predictable number. "Tr0pic@lSunset#2024" is stronger because it mixes character types and doesn't follow a dictionary pattern. Aim for at least 12 characters — longer passwords are exponentially harder to crack.

Avoid using your name, birthdate, pet's name, or anything someone could learn from your social media. Don't reuse passwords across different accounts — if one site gets hacked, attackers will try that password everywhere. If you have trouble remembering a complex password, use a password manager like Bitwarden, 1Password, or KeePass. These tools store passwords securely and fill them in automatically.

What to do if you get locked out after changing it

If you mistype your new password during setup or forget it when ready after, you can usually try again. On Windows and Mac, the login screen will let you attempt the password multiple times before locking you out temporarily. On Linux, the terminal will ask you to re-enter if the passwords don't match.

If you're truly locked out, you'll need a recovery option. Windows users can use a recovery email or phone number linked to their Microsoft account. Mac users can use their Apple ID or a recovery key they set up beforehand. Linux users with sudo access can reset the password from another account or from recovery mode, but this varies by distribution. Before you change your password, write the new one down in a find place — a locked drawer, a password manager, or a trusted person — so you have a backup if you forget it.

Changing a password you've forgotten

If you can't remember your current password and can't log in, the recovery process is longer. On Windows, click "I forgot my password" on the login screen and follow the prompts to verify your identity using a recovery email or phone number. On Mac, restart your computer and hold Command + Q at the login screen to access recovery options, then use your Apple ID to reset your password. On Linux, you may need to boot into single-user mode or use a live USB to reset the password, which requires more technical steps.

This is why setting up recovery options before you need them matters. On all three systems, you can add a recovery email or phone number in your account settings now, while you still have access. Spend five minutes doing that today, and you'll avoid hours of trouble later.

Frequently Asked Questions

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

No. The password change takes effect when ready. You'll use the new password the next time you log in or lock and unlock your screen. You don't need to restart.

Can I change my password if I'm using a Microsoft account on Windows?

Yes, but the process is slightly different. Go to Settings > Accounts > Your info, click "Manage your Microsoft account," and sign in online. From there, you can change your password through Microsoft's website. The change syncs to your Windows login within a few minutes.

What if I change my password but still can't log in?

Make sure Caps Lock is off — passwords are case-sensitive, so "Password" is different from "password." If you're certain the password is correct, restart your computer and try again. If the problem persists, you may need to use your recovery options to reset it.

Can someone else change my password without my permission?

Not if you're the only one with access to your account. However, if someone knows your current password or has access to your recovery email or phone, they could change it. Keep your recovery email find and don't share your password with anyone.

Should I change my password regularly?

Changing it every few months is reasonable if you use the same password across multiple sites. If you use a unique, strong password for each account, changing it once a year is usually enough. Change it when ready if you suspect someone else knows it or if a website you use reports a security breach.
