The fastest way to change your password depends on your operating system

On Windows, you open Settings, go to Accounts, select "Password," and click "Change." On a Mac, you open System Settings, go to General, click "Login Items & Extensions," then select your user account and click "Password." Both take about two minutes. The steps differ because Windows and Mac store passwords differently, but the goal is the same: you're replacing the old password your computer uses to verify it's really you when you log in.

Before you start, write down your new password somewhere safe—not in a note on your desktop. A physical notebook, a password manager like Bitwarden or 1Password, or even a sealed envelope in a drawer all work better than a text file. If you forget the new password before you've used it a few times, you'll need to reset your account, which is more complicated than just changing it now.

Key Takeaways

  • Windows users find the password change tool in Settings > Accounts > Password, while Mac users go to System Settings > General > Login Items & Extensions.
  • You will need to type your current password first to prove you have the right to change it.
  • Your new password should be at least 8 characters long and include uppercase letters, numbers, and symbols to resist guessing.
  • Store your new password in a password manager or physical location before you log out, so you don't lock yourself out.

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. Once Settings opens, click "Accounts" on the left side of the window.

In the Accounts menu, click "Password" in the left column. You'll see a button that says "Change." Click it. Windows will ask you to type your current password to confirm you're the account owner—this is a security step, not a mistake. Type it and click "Next."

Now you'll see three fields: "Create password," "Reenter password," and "Password hint." Type your new password in the first field. Type it again in the second field to make sure you didn't make a typo. The password hint is optional—it's a phrase only you will see if you forget the password, so make it something meaningful to you but not obvious to someone else. Click "Next," then "Finish." Your password is now changed.

Step-by-step for Mac

Click the Apple menu in the top-left corner of your screen. Select "System Settings" from the dropdown. In System Settings, click "General" in the left sidebar.

Scroll down and click "Login Items & Extensions." You'll see a list of user accounts. Find your own account name and click it. A button labeled "Password" will appear. Click it. macOS will ask you to type your current password—this confirms you're authorized to make the change. Type it and click "OK."

A new window opens with two fields: "New Password" and "Verify." Type your new password in the first field, then type it again in the second field to catch any typos. Click "Change Password." You're done. The next time you log in, use the new password.

What makes a strong password that's hard to guess

A strong password is at least 12 characters long and mixes uppercase letters, lowercase letters, numbers, and symbols. "MyDog2024!" is stronger than "password123" because it combines different types of characters. Avoid using your name, your birth year, or words that appear in the dictionary—these are the first things someone trying to break in will try.

The best passwords are random or nonsensical: "Tr0pic@lPenguin42" or "Blender#Sock8Maple" are both hard to guess because they don't follow a pattern. If you can't remember a random password, use a password manager. It stores the password encrypted on your computer and fills it in automatically when you log in. You only have to remember one strong password to unlock the manager itself.

What to do if you forget your new password right after changing it

On Windows, restart your computer and try logging in with the new password. If you typed it wrong during the change, Windows might still accept your old password. If neither works, click "Reset password" on the login screen. Windows will ask you security questions or send a code to your email address—whichever method you set up when you created your account. Answer correctly and you can set a new password.

On a Mac, restart and try the new password at the login screen. If it doesn't work, click "?" at the bottom of the login window. macOS will show your password hint. If that doesn't help, restart again and hold Command + S to enter Recovery Mode. From there you can reset your password, though the process is longer. This is why writing down your new password before you log out is worth the small security trade-off.

Why your computer asks for a password at all

Your computer password is the first line of defense if someone gains physical access to your machine. Without it, anyone who sits down at your desk can read your files, send emails from your account, or install software. The password doesn't protect you from hackers on the internet—that's what your firewall and antivirus do—but it does protect you from someone in your home, office, or coffee shop.

Changing your password every few years is a reasonable practice, especially if you've shared it with someone who no longer needs access or if you suspect someone may have seen it. You don't need to change it every month unless your workplace requires it. A password you change too often becomes a password you write down, which defeats the purpose.

Changing your password on a work or school computer

If your computer is managed by an employer or school, the password change process may be different. Your IT department may require you to use a specific tool or may have locked the Settings menu so you can't change it yourself. Check your employee handbook or IT support page first. Many organizations require passwords to meet specific rules—a minimum length, a mix of character types, or a rule against reusing old passwords.

If you're locked out of the password change tool, contact your IT help desk. They can reset your password for you or walk you through the correct process for your organization's system. Don't try to work around the restrictions—they exist to keep company data find, and bypassing them can violate your employment agreement.

Frequently Asked Questions

Will changing my password affect my files or programs?

No. Your password only controls who can log in. Your files, programs, and settings stay exactly where they are. The only thing that changes is what password you type at the login screen.

Do I need to change my password if I'm the only person who uses my computer?

Not urgently. If you live alone and no one else has physical access, changing your password once every few years is enough. If you share your home or office, or if you suspect someone has seen your password, change it sooner.

What if I set a password hint and now I'm worried it's too obvious?

On Windows, you can change the hint without changing your password. Go back to Settings > Accounts > Password and click "Change password hint." On a Mac, the hint is harder to modify without resetting the whole password. If you're concerned, it's simpler to just change your password again and set a new hint.

Can I use the same password on my computer as I use for email or banking?

It's not recommended. If someone breaks into one account, they can try that same password on others. Use a different password for each important account—your computer, email, banking, and social media should all be different. A password manager makes this easier by remembering all of them for you.

What happens if I change my password and then my computer crashes?

Your new password is saved to your computer's system files, so a crash won't erase it. When you restart, you'll log in with the new password just as normal. The password change is permanent once you click Finish or Change Password.
