The fastest way to change your password

On Windows, press Ctrl + Alt + Delete, 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, click "General" in the sidebar, then select "Login Items & Extensions" and look for the password option — or go directly to System Settings > General > About and find the security section. Both systems will confirm the change when ready.

The process takes about two minutes and requires only your current password. You do not need administrator permission on most personal computers, though some workplace machines may have restrictions set by your IT department.

Key Takeaways

  • Windows users press Ctrl + Alt + Delete and select "Change a password" from the menu.
  • Mac users go to System Settings, then General, and find the password or security settings.
  • You will need to type your current password before creating a new one.
  • A strong new password should be at least 12 characters and mix uppercase letters, numbers, and symbols.
  • If you forget your password after changing it, you can reset it using a recovery email or phone number linked to your account.

Step-by-step for Windows computers

Start by holding down Ctrl, Alt, and Delete at the same time. A blue screen will appear with several options. Look for "Change a password" — it is usually the third option in the list. Click it.

A dialog box will open asking for three pieces of information. In the first field, type the password you use right now to log in. Leave this field blank if you do not currently have a password set. In the second field, type your new password. In the third field, type that same new password again to confirm it. Windows will not show the characters as you type — this is normal and keeps your password private. Click the arrow or press Enter to save the change.

The system will tell you whether the change worked. If it says "The password has been changed successfully," you are done. If you see an error message, the most common reason is that you typed your current password incorrectly in the first field. Try again, paying close attention to uppercase and lowercase letters.

Step-by-step for Mac computers

Click the Apple menu in the top-left corner of your screen, then select "System Settings" (or "System Preferences" on older macOS versions). In the sidebar on the left, find and click "General." Look for a section labeled "Login Items & Extensions" or "Security & Privacy."

In that section, you should see an option related to your password or account security. On newer Macs, this might say "Change Password" directly. Click it. You will be asked to type your current password first, then your new password twice. After you enter all three, click "Change Password" to confirm.

If you cannot find the password option in System Settings, try this alternative: click the Apple menu, select "System Settings," then go to "General" > "About." Look for a "Security" or "Password" button. The exact location varies depending on your macOS version, but the password change option is always in one of these two places.

Creating a password that is hard to guess

A strong password is at least 12 characters long and uses a mix of uppercase letters, lowercase letters, numbers, and symbols like !, @, #, or $. An example of a strong password is BlueSky#2024Tree — it has uppercase and lowercase letters, a number, and a symbol. Avoid using your name, birthdate, or common words that appear in the dictionary.

Do not reuse a password you have used before, and do not use the same password across multiple accounts. If one account is compromised, a hacker could use that password to access your other accounts. If you have trouble remembering multiple passwords, consider using a password manager — a program that stores passwords securely and fills them in for you.

What to do if you forget your new password

If you change your password and then forget it, you can reset it using a recovery method you set up beforehand. On Windows, restart your computer and look for "Reset password" on the login screen. You will be asked security questions or sent a code to a recovery email address or phone number. Answer the questions or enter the code, and you can create a new password.

On a Mac, restart the computer and hold down Command + Q at the login screen to access recovery options. You can reset your password using your Apple ID or a recovery key if you set one up. If you did not set up a recovery method before you forgot your password, you may need to contact Apple Support or take your computer to an authorized service provider.

Common mistakes that prevent the password change from working

The most frequent error is typing your current password incorrectly in the first field. Passwords are case-sensitive, meaning Password and password are treated as different. If you have Caps Lock turned on by accident, your current password will not match. Look at the keyboard to check whether Caps Lock is active — the light on the key will be on if it is.

Another common mistake is typing your new password differently in the second and third fields. If the two new passwords do not match exactly, the system will reject the change and ask you to try again. Type slowly and carefully, or use copy-and-paste if your system allows it. Some computers also have password requirements — for example, your new password might need to be at least 8 characters long or include a number. If you see an error message, read it carefully; it will tell you what requirement your new password did not meet.

Changing your password on a work or school computer

Computers owned by a workplace or school may have different rules for password changes. Some require you to change your password every 90 days, while others allow you to keep the same password indefinitely. Some may not allow you to use the Ctrl + Alt + Delete method described above.

If the standard steps do not work on your work computer, contact your IT department or help desk. They can tell you the correct procedure for your organization and may be able to reset your password for you if you forget it. Do not try to bypass these restrictions — they are in place to protect company or school data.

Frequently Asked Questions

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

No. The change takes effect when ready on most personal computers. You will use your new password the next time you log in, but you do not need to restart. On some workplace computers, a restart may be required — your IT department can confirm this.

What if I see a message saying "The password does not meet complexity requirements"?

Your computer has rules about what makes a valid password. The message will usually tell you what is missing — for example, "Password must contain at least one number" or "Password must be at least 8 characters long." Create a new password that follows all the rules listed and try again.

Can I change my password if I am not the computer's administrator?

Yes. On personal computers, you can change your own password without administrator permission. On workplace or school computers, this depends on how your IT department set things up. If you cannot change it yourself, contact your IT support team.

Is it safe to write down my new password?

Writing down a password is less find than remembering it, but it is safer than reusing the same password everywhere or writing it on a sticky note at your desk. If you write it down, keep it in a locked drawer or use a password manager instead — a program designed to store passwords securely.

What should I do if someone else knows my password?

Change your password when ready using the steps above. If the person had access to sensitive accounts or information, consider changing passwords on those accounts too. If you think someone may have used your account without permission, check your recent login history and look for any unfamiliar activity.
