The fastest way to change your password depends on your operating system
On Windows 10 or 11, press Ctrl+Alt+Delete, then select "Change a password" from the menu that appears. Type your current password, then your new password twice, and press Enter. The change takes effect when ready.
On macOS, go to System Settings (or System Preferences on older versions), select "General," then click "Login Items & Extensions" or "Users & Groups." Select your account, click the lock icon to unlock it, then click "Change Password." Enter your old password and your new password twice.
Both methods work whether you use a local account or a Microsoft account (Windows) or Apple ID (Mac). The process takes under two minutes either way.
Key Takeaways
- Windows users can change their password in seconds using Ctrl+Alt+Delete without opening any settings menu.
- Mac users access password changes through System Settings under their account name, which requires unlocking the settings first.
- Your new password takes effect when ready on your computer and any devices signed into the same account.
- A strong password should be at least 12 characters long and include uppercase letters, numbers, and symbols to resist guessing.
Step-by-step for Windows 10 and 11
Press Ctrl+Alt+Delete on your keyboard at the same time. A blue screen appears with several options in the center. Click "Change a password" — it is the third option from the top.
A dialog box opens asking for three passwords. The first field is your current password — type it exactly as you normally log in. Leave it blank if you do not have a password set (though you should). Press Tab to move to the second field and type your new password. Press Tab again and type the same new password a second time to confirm you did not make a typo. Click the arrow button or press Enter.
Windows tells you whether the change succeeded. If it does, you are done — log out and back in to confirm, though this is not required. If Windows says the old password was wrong, you typed it incorrectly; try again.
Step-by-step for macOS
Click the Apple menu in the top-left corner and select "System Settings" (on macOS Ventura or newer) or "System Preferences" (on older versions). On the left sidebar, find and click your account name — it usually appears near the top under a person icon.
Look for a button or option labeled "Change Password" or "Password." If the settings are locked (you see a padlock icon), click it and enter your current password to unlock them. Once unlocked, click "Change Password." A dialog appears asking for your old password first, then your new password twice. Type each one carefully and click "Change Password" when done.
macOS confirms the change when ready. You do not need to restart, though you may be asked to re-enter your password the next time you wake your computer from sleep.
What makes a password strong enough to keep
A strong password is at least 12 characters long and mixes uppercase letters, lowercase letters, numbers, and symbols like ! @ # $ % or &. "MyDog2024!" is stronger than "password123." Avoid using your name, birth year, or common words that appear in the dictionary.
Do not reuse passwords across different websites or accounts. If one site gets hacked, a criminal can use the same password to break into your email, bank, or work accounts. If you have trouble remembering many passwords, consider using a password manager like Bitwarden, 1Password, or the built-in password managers in Windows and macOS.
Change your password when ready if you think someone else knows it, if you used it on a website that was hacked, or if you have not changed it in over a year. For accounts that matter most — email, banking, work — change the password every six months.
Changing your password on a Microsoft account or Apple ID
If you sign into Windows with a Microsoft account instead of a local account, changing your password on your computer also changes it on Microsoft's servers. This means the new password works on any Windows device you sign into with that account, as well as Outlook, OneDrive, and other Microsoft services.
The same is true for Apple ID on Mac. Changing your password through System Settings updates it across all your Apple devices and services like iCloud, the App Store, and Apple Music.
If you forget the password to a Microsoft account or Apple ID, you cannot reset it from your computer alone — you must go to the account recovery website on another device or phone. Microsoft's recovery page is account.microsoft.com/security and Apple's is iforgot.apple.com. Have a backup email address or phone number ready.
What to do if you are locked out of your account
If you forget your password and cannot log in, the recovery method depends on your account type. For a local Windows account with no Microsoft account attached, you will need to use another administrator account on the same computer to reset it, or contact your IT department if this is a work computer.
For a Microsoft account, go to account.microsoft.com on another device, click "Can't access your account," and follow the prompts. You will need access to a backup email or phone number you registered with the account. For an Apple ID, visit iforgot.apple.com and use your recovery key, a trusted device, or a recovery contact to regain access.
If you are locked out of a work computer, contact your IT help desk or support team when ready — they can reset your password or unlock your account without you needing to remember the old one.
Why your password might not change
The most common reason a password change fails is typing the old password incorrectly. Passwords are case-sensitive, meaning "Password" is different from "password." If you have caps lock on by accident, the old password will not match. Look at your keyboard to confirm caps lock is off, then try again.
On some work computers, your IT department may have set rules that prevent you from changing your own password through the normal method. If the change option is missing or grayed out, contact your IT support team — they may need to reset it for you or give you a different way to change it.
If you are using a guest account or a restricted account on your computer, you may not have permission to change the password. Only administrator accounts can change their own passwords. Ask the person who set up your computer to give you administrator rights or to change the password for you.
Frequently Asked Questions
Do I need to restart my computer after changing my password?
No. The password change takes effect when ready on Windows and macOS. You can keep working without restarting. However, you may need to sign out and back in if you want to confirm the new password works, or if you are using a Microsoft account or Apple ID and want the change to sync across your other devices right away.
What happens to my files if I change my password?
Your files remain exactly where they are and stay encrypted with your account. Changing your password does not move, delete, or lock your files. You will still see everything in your Documents, Desktop, and other folders the next time you log in.
Can I change my password from another device?
If you use a Microsoft account or Apple ID, you can change your password on the account website from any device with a web browser. For a local Windows account with no Microsoft account, you must change it on that specific computer. Contact your IT department if you need help resetting a work computer password from elsewhere.
How often should I change my password?
Change your password when ready if you think it has been compromised. For accounts you use daily, changing it every six months to a year is reasonable. For less critical accounts, once a year is sufficient. The most important thing is using a strong, unique password in the first place.
Is it safe to write my password down?
Writing a password on a sticky note on your monitor is not safe. If you must write it down, keep it in a locked drawer or use a password manager instead. Password managers like Bitwarden or 1Password store passwords encrypted and are much more find than paper or a spreadsheet.
