How to change your password depends on your operating system
The steps differ between Windows, macOS, and Linux, but the principle is the same: you go into your system settings, find the user account section, and replace your old password with a new one. On Windows, you use Settings > Accounts > Your Info. On a Mac, you go to System Settings > General > Login Items, then click the lock icon and change your password there. On Linux, the method varies by distribution, but most desktop environments let you right-click your user account in Settings and select "Change Password" or similar.
The entire process takes about five minutes on any system. You'll need to know your current password to verify you have permission to change it — the system won't let you change a password without proving you're the account owner. After you set a new password, you'll use that new one the next time you log in.
Key Takeaways
- Windows users go to Settings > Accounts > Your Info, click "Password," then "Change" to set a new password.
- Mac users open System Settings > General > Login Items, click the lock icon, and select "Change Password" from the user menu.
- Linux users typically find password options in Settings under User Accounts, though the exact path depends on your desktop environment.
- You must enter your current password before creating a new one, as a security check that you own the account.
- Your new password takes effect immediately on your next login — you don't need to restart the computer.
Changing your password on Windows 10 or 11
Open Settings by pressing the Windows key and typing "Settings," then press Enter. Click "Accounts" in the left sidebar. Select "Your Info" at the top. You'll see a "Password" section with a blue "Change" button — click it.
Windows will ask you to enter your current password to confirm you're the account owner. Type it in and click "Next." Then create your new password in the first field, type it again in the second field to confirm you didn't make a typo, and optionally add a password hint (though this is not required). Click "Next," then "Finish." Your new password is now active.
If you've forgotten your current password, you cannot use this method. Instead, you'll need to use a password reset disk (if you created one earlier) or a Microsoft account recovery process, which involves verifying your identity through a backup email or phone number.
Changing your password on macOS
Click the Apple menu in the top-left corner and select "System Settings." Click "General" in the sidebar, then scroll down and click "Login Items." You'll see a lock icon near the bottom of the window — click it and enter your current password when prompted.
Once the lock is open, look for your user account name in the list and click it. A menu will appear with options including "Change Password." Click that option. Enter your current password, then type your new password twice (once to set it, once to confirm), and click "Change Password." The change takes effect immediately.
On older Macs running earlier versions of macOS, the path is slightly different: go to System Preferences > Users & Groups, click the lock icon, select your account, and click "Change Password." The steps after that are the same.
Changing your password on Linux
The exact steps depend on which Linux distribution and desktop environment you're using. On Ubuntu with GNOME, click the system menu (usually in the top-right corner), select "Settings," then click "Users" in the sidebar. You may need to click a lock icon and enter your password to unlock user settings.
Find your user account in the list and click it. Look for a "Password" field or button — on some versions it says "Change Password." Click it, enter your current password, type your new password twice, and confirm. On Fedora, Debian, or other distributions, the path is similar but may be labeled slightly differently — look for "Users," "Accounts," or "User Settings" in your system settings.
If you prefer the command line, you can also use the passwd command in a terminal. Open a terminal and type passwd, then press Enter. The system will ask for your current password, then prompt you to enter your new password twice. This method works on any Linux distribution.
Creating a strong password you can actually remember
A strong password is at least 12 characters long and includes uppercase letters, lowercase letters, numbers, and symbols. But a password that's impossible to remember is useless — you'll write it down or reuse it across multiple accounts, both of which defeat the purpose.
A practical approach is to use a passphrase: a string of random words strung together, like "coffee-umbrella-tuesday-47." This is easier to remember than a random string of characters, harder to guess than a word, and meets length requirements. Alternatively, use a password manager like Bitwarden, 1Password, or KeePass to generate and store strong passwords — you only have to remember one master password, and the manager handles the rest.
Avoid passwords based on personal information (your name, birthday, pet's name), dictionary words, or simple patterns like "password123." These are the first things attackers try. Also avoid reusing the same password across multiple accounts — if one service is breached, attackers will try that password on your email, banking, and social media accounts.
What to do if you forget your password
On Windows, you have a few options. If you set up a password reset disk before you forgot your password, you can use it to create a new one. If you use a Microsoft account (rather than a local account), you can reset your password from the Windows login screen by clicking "I forgot my password" and verifying your identity through a backup email or phone number. If you have neither, you'll need to contact Microsoft support or use a local administrator account if one exists on your computer.
On a Mac, if you set up a recovery key or have another administrator account on the computer, you can use those to reset your password. If not, you can restart in Recovery Mode (hold Command-R while the computer starts up), open Utilities > Terminal, and use the resetpassword command. On Linux, you can boot into single-user mode or recovery mode and reset your password from there, though the exact steps depend on your distribution.
The easiest prevention is to write your password down and store it somewhere physically secure — a locked drawer, a safe, or a notebook you keep at home. This is more secure than reusing passwords or writing them on a sticky note on your monitor.
Why you might want to change your password regularly
You should change your password immediately if you suspect someone else knows it, if you used it on a website that was breached, or if you shared it with someone who no longer needs access. You don't need to change it on a fixed schedule (like every 90 days) unless your workplace or school requires it — regular changes don't actually improve security if your password wasn't compromised.
What matters more is using a unique password for each important account (especially email and banking), using a strong password, and changing it only when there's a reason to. If you reuse the same password across multiple sites and one site is breached, attackers will try that password on your email, bank, and social media. Changing your computer password won't protect those accounts — you'd need to change the password on each individual service.
Frequently Asked Questions
Do I need to restart my computer after changing my password?
No. Your new password takes effect immediately. The next time you log out and log back in, or the next time you wake your computer from sleep, you'll use the new password. You don't need to restart.
What if I change my password and then forget the new one?
On Windows, you can use a password reset disk or Microsoft account recovery if you set those up beforehand. On Mac, you can use a recovery key or another administrator account. On Linux, you can boot into recovery mode. If you have none of these, you may need to reinstall your operating system, which will erase your files. This is why keeping a backup password somewhere safe is important.
Can I change my password without knowing my current password?
No. The system requires you to enter your current password as proof that you own the account. This prevents someone else from walking up to your computer and changing your password. If you've forgotten your current password, you'll need to use a recovery method specific to your operating system.
Does changing my computer password change my email or social media passwords?
No. Your computer password only controls access to your computer itself. Your email, social media, banking, and other online accounts have separate passwords that you change through those services' own settings. If you want to change all your passwords, you'll need to do each one individually.
Is it safe to use the same password for my computer and my email?
No. If someone gains access to your email account, they can use the password reset feature on other services to take over your accounts. Keep your email password separate and especially strong, and use unique passwords for other important accounts like banking and social media.
