Change your password through your computer's settings, not through a website

The fastest way to change your PC password is to use your computer's built-in settings, not a password manager or a website. On Windows, press Ctrl + Alt + Delete, then select "Change a password." On a Mac, go to System Settings (or System Preferences on older versions), then General > Login Items & Security > Password, and click the lock icon to make changes. Both methods let you set a new password when ready without restarting.

If you cannot remember your current password, the process is different — you will need to use a password reset disk (if you created one before) or answer security questions you set up earlier. Windows and Mac both have recovery options, but they work only if you prepared them ahead of time. If you have not prepared a recovery method and cannot log in, you may need to contact your computer manufacturer's support line or take your device to a technician.

Key Takeaways

  • Windows users press Ctrl + Alt + Delete and select "Change a password" to update their login password without restarting.
  • Mac users open System Settings, navigate to General > Login Items & Security > Password, unlock the section, and enter a new password.
  • A strong password contains at least 12 characters and mixes uppercase letters, lowercase letters, numbers, and symbols — avoid birthdays, names, or dictionary words.
  • If you forget your password, you will need a password reset disk or security questions you set up before the problem happened.
  • Changing your computer password does not automatically change passwords for email, social media, or other online accounts — those require separate updates.

What makes a password strong enough to protect your account

A strong computer password is long and mixed. Aim for at least 12 characters. Use uppercase letters, lowercase letters, numbers, and symbols (like !, @, #, $, %) all together. A password like BlueMoon#2024River is stronger than password123 because it mixes character types and does not follow a predictable pattern.

Avoid passwords based on information someone could guess or find about you: your name, your birthday, your pet's name, your street address, or common words in the dictionary. Avoid repeating the same password across multiple accounts — if one account is breached, attackers will try that password on your email, banking, and social media. If you use the same password everywhere and one site is compromised, every account becomes vulnerable.

Do not write your password on a sticky note on your monitor or in an unencrypted document on your desktop. If you struggle to remember a strong password, a password manager like Bitwarden, 1Password, or KeePass stores passwords in an encrypted vault that you unlock with one main password. This way you only have to remember one strong password instead of dozens.

Windows: step-by-step password change

On any Windows computer, the quickest route is the keyboard shortcut. Press Ctrl + Alt + Delete all at once. A menu will appear with several options. Click "Change a password" (the exact wording may vary slightly by Windows version). You will see three fields: "Old password," "New password," and "Confirm new password."

Type your current password in the first field. Then type your new password in the second field. Type it again in the third field to confirm you did not make a typo. Windows will tell you if the passwords do not match or if your new password is too weak. Once you see a confirmation message, your password has changed. You do not need to restart your computer — the new password takes effect when ready.

If the Ctrl + Alt + Delete shortcut does not work, you can also change your password through Settings. Click the Windows Start button, then Settings > Accounts > Sign-in options > Password > Change. This route asks you to verify your identity (usually by entering your current password or a PIN) before letting you set a new one.

Mac: step-by-step password change

On a Mac, open System Settings (called System Preferences on macOS Monterey and earlier). In the sidebar, click General. Then click Login Items & Security (or just Security & Privacy on older versions). Look for the Password section. You will see a lock icon — click it and enter your current password to unlock the settings.

Once unlocked, click the Change Password button. A dialog box will open asking for your old password, then your new password twice. Type carefully — you cannot see what you are typing, so confirming the new password twice prevents typos. Click Change Password to save. Your Mac will ask you to update your keychain password (the encrypted storage for passwords and sensitive information on your Mac) — click Update Keychain so your stored passwords stay accessible.

If you do not see a Password option in Login Items & Security, your Mac may use a different authentication method (like Touch ID or a security key). You can still change your password by clicking the Apple menu > System Settings > General > About, then looking for a "Change Password" button, though the exact location varies by macOS version.

What happens to your other accounts when you change your computer password

Changing your computer login password does not change the passwords for your email, social media, banking, or any other online accounts. Your computer password only controls who can log into that specific device. If you want to update your email password, you must go to your email provider's website or app and change it there. The same applies to every other account — each one has its own password that you control separately.

This separation is actually a safety feature. If someone steals your computer password, they can access your device, but they cannot automatically access your Gmail, Facebook, or bank account unless they also know those passwords. However, if they gain access to your computer, they may be able to see passwords you have saved in your browser or read emails on your device — so changing your computer password quickly after a breach is still important.

If you forget your computer password

If you cannot remember your Windows password, Windows offers a few recovery paths. If you set up a password reset disk before you forgot your password, you can use it to create a new one. Insert the reset disk, click "Reset password" on the login screen, and follow the prompts. If you did not create a reset disk, you can answer security questions you set up earlier (like "What was the name of your first pet?") — but only if you answered them when you first set up your account.

On a Mac, if you forget your password, you can use your Apple ID to reset it. At the login screen, click the question mark or "Reset Password" option, then enter your Apple ID and follow the prompts. You will need access to the phone number or email address associated with your Apple ID. If you do not have access to your Apple ID or did not link one to your account, you may need to contact Apple Support or take your Mac to an Apple Store.

The lesson here is to prepare before you need it: create a password reset disk on Windows, write down your security questions and answers in a safe place, or make sure your Apple ID is linked to your Mac and that you can access the email or phone number tied to it. Once you are locked out without these recovery methods, the only option is usually a technician or manufacturer support.

How often you should change your computer password

You do not need to change your computer password every month just to be safe. If your password is strong and unique, and you have not noticed any suspicious activity on your device, changing it once a year or less often is reasonable. However, you should change your password when ready if you suspect someone else knows it, if you used the same password on a website that was breached, or if you shared your device with someone who no longer has permission to use it.

If your computer was stolen or you used it on an unsecured public WiFi network where someone could have intercepted your password, change it as soon as you can access another device. The same applies if you notice unfamiliar programs running, files you did not create, or login attempts from places you do not recognize. These signs suggest someone may have gained access to your device, and a password change is one step to regain control.

Frequently Asked Questions

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

No. On both Windows and Mac, the new password takes effect when ready. You can continue working without restarting. The next time you log out and log back in, or the next time you wake your computer from sleep, you will use the new password.

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

On Windows, you can use your password reset disk or security questions to create another new password. On a Mac, you can use your Apple ID to reset it. If you do not have either option set up, you will need to contact support or visit a technician. This is why writing down your new password in a find location (like a locked drawer or a password manager) is helpful until you memorize it.

Can I use the same password I used before?

Technically yes, but it defeats the purpose of changing your password. If you changed it because you thought someone knew the old one, reusing it leaves you vulnerable. If you changed it for routine security, reusing an old password is less risky but still not ideal. Choose a new, strong password instead.

Will changing my computer password affect my WiFi connection?

No. Your computer password and your WiFi password are separate. Changing your computer login password does not disconnect you from WiFi or require you to re-enter your WiFi password. Your WiFi connection will continue working normally.

What if I see a password change prompt I did not ask for?

Be cautious. If a popup appears on your screen asking you to change your password without you initiating it, do not enter your password into that popup. Close it and change your password through your official Settings instead (Ctrl + Alt + Delete on Windows, or System Settings on Mac). Unsolicited password prompts can be malware trying to steal your credentials.
