The fastest way depends on whether you use Windows or Mac

On Windows 10 or 11, you can change your password by pressing Ctrl+Alt+Delete, selecting "Change a password", and typing your old password followed by your new one twice. On a Mac, you go to System Settings, click General, then Users & Groups, unlock the settings with your current password, right-click your account, and select "Change Password". Both take about two minutes if you remember your current password.

If you have forgotten your password entirely, the process is longer — you will need to use a recovery method like a backup email address or phone number you set up earlier, or answer security questions. This guide covers the standard password change first, then walks through what to do if you are locked out.

Key Takeaways

  • Windows users press Ctrl+Alt+Delete and select "Change a password" to update their login password in seconds.
  • Mac users open System Settings, navigate to Users & Groups, and select "Change Password" from the account menu.
  • You will need your current password to change it — if you have forgotten it, you must use a recovery email or phone number instead.
  • A strong new password should be at least 12 characters long and mix uppercase letters, numbers, and symbols to prevent unauthorized access.
  • After you change your password, you may need to sign back into apps and cloud services that store your old password.

Changing your password on Windows 10 or 11

The quickest method on any Windows machine is the Ctrl+Alt+Delete shortcut. Press those three keys at the same time, and a blue screen will appear with several options. Click "Change a password" — it is usually the third option on the list. You will see three fields: one for your current password, one for your new password, and one to confirm the new password by typing it again.

Type your current password first. Then type your new password in the second field. Type the exact same new password in the third field — if the two do not match, Windows will reject the change. Press Enter or click the arrow button, and you will see a message saying your password has been changed. You can then log in normally the next time you restart your computer or lock your screen.

If the Ctrl+Alt+Delete method does not work on your machine, you can also change your password through Settings. Click the Start button, type "password" into the search box, and select "Change your password" from the results. This opens the same three-field form and works identically.

Changing your password on a Mac

On macOS, open System Settings (called System Preferences on older Macs). Click "General" in the sidebar, then look for "Users & Groups" or "Login Items" — the exact name depends on your macOS version. You may see a lock icon at the bottom of the window; if so, click it and type your current password to unlock the settings.

Find your account name in the list on the left side of the window. Right-click it (or click while holding Control), and a menu will appear. Select "Change Password" from that menu. You will be asked to type your current password first, then your new password twice. Once you confirm, the change takes effect when ready.

On very recent Macs running macOS Ventura or later, the path is slightly different: go to System Settings, click "General", then "Login Items & Extensions", and look for your account in the Users section. The password change process is the same once you find your account.

What to do if you have forgotten your current password

If you cannot remember your password, you cannot use the standard change method — both Windows and Mac require you to type your old password first. Instead, you will need to use a recovery method. On Windows, click "I forgot my password" on the login screen. Windows will ask you to verify your identity using a backup email address, a phone number, or security questions you answered when you created your account.

Once you verify your identity, Windows will let you create a new password without typing the old one. This process can take a few minutes, and you may need to restart your computer. If you did not set up a recovery email or phone number when you created your account, you may need to contact Microsoft support or use a Windows installation disk to reset your password — this is more involved and can take longer.

On a Mac, restart your computer and hold Command+Q as it boots up to enter Recovery Mode. Click "Utilities" in the menu bar, then "Reset Password". Select your account from the list, and you will be prompted to create a new password. You do not need to type your old password in this mode. After you set a new password, restart normally and log in with the new one.

Creating a strong password you will not forget

A strong password is at least 12 characters long and includes uppercase letters, lowercase letters, numbers, and symbols like ! @ # $ % or &. Avoid using your name, your birth year, or common words that appear in the dictionary — these are straightforward for others to guess. A phrase like "BlueMoon$42!Coffee" is stronger than "Password123" because it mixes character types and is harder to predict.

Write your new password down in a find place — a locked drawer, a safe, or a password manager like Bitwarden or 1Password. Do not email it to yourself or leave it in a text file on your desktop. If you use the same password across multiple accounts, change that habit now; if one account is compromised, all of them are at risk. A password manager can generate and store unique passwords for each service, so you only have to remember one strong master password.

What happens after you change your password

Once you change your Windows or Mac password, you will be logged out of most cloud services and apps that were using your old password. Microsoft Outlook, Gmail, OneDrive, iCloud, and similar services may ask you to sign in again. This is normal and a security feature — it ensures that only devices you actively authorize can access your accounts.

If you use your Microsoft or Apple account to sign into other devices — a phone, tablet, or another computer — you will need to update the password on those devices too. Go to the settings on each device and re-enter your new password when prompted. This usually happens automatically the next time you try to use a cloud service, but you can speed it up by signing out and signing back in manually.

Troubleshooting password change problems

If you see an error message saying your password does not meet the requirements, it means your new password is too short, does not have enough character variety, or contains a word that is too common. Try adding a number and a symbol, or making it longer. Windows and Mac both have minimum requirements — usually at least 8 characters, with a mix of uppercase and lowercase letters.

If you change your password but still cannot log in, restart your computer and try again. Sometimes the system needs a moment to sync the change across all services. If you are still locked out after a restart, use the recovery method described above to reset your password a second time. If you are on a work computer, contact your IT department — they may have additional security rules that prevent certain passwords or require you to change your password through a company portal instead.

Frequently Asked Questions

Can I change my password without restarting my computer?

Yes. On Windows, use Ctrl+Alt+Delete or the Settings search method — both let you change your password while you are logged in. On Mac, the System Settings method works the same way. You do not need to restart unless you want to verify the new password works on the login screen.

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

Use the recovery method for your operating system. On Windows, click "I forgot my password" on the login screen and verify your identity with your backup email or phone. On Mac, restart and hold Command+Q to enter Recovery Mode, then use "Reset Password" from the Utilities menu. Both methods let you create another new password without typing the old one.

Do I need to change my password on my phone too?

Only if you use your Microsoft or Apple account to sign into your phone. If your phone is linked to your computer account, you will need to update the password in your phone's settings so it can continue to sync email, photos, and other data. Check your phone's Settings under Accounts or Cloud Services.

How often should I change my password?

Change it when ready if you think someone else knows it or if you have used it on a website that was hacked. Otherwise, changing it once or twice a year is reasonable for personal computers. Work computers often have policies requiring changes every 30 to 90 days — check with your IT department for their rules.

Can I use the same password on multiple devices?

You can, but it is not recommended. If one device is compromised, all of them are at risk. Use a password manager to create and store different strong passwords for each device, so you only have to remember one master password.
