The fastest way depends on which operating system you use
On Windows 10 or 11, you change your password through Settings. On a Mac, you use System Settings. Both take about five minutes and require you to know your current password first — if you have forgotten it, the process is different and longer. The steps below cover the most common setup: a personal computer where you are the administrator.
If you are on a work laptop, your IT department may have locked down password changes or required you to use their own system. Check with them before you start, because some corporate setups will not let you change it through the standard method.
Key Takeaways
- Windows users go to Settings > Accounts > Sign-in options and select "Password" to change it.
- Mac users go to System Settings > General > Login Items & Extensions, then click the lock icon and select "Change Password".
- You will need to enter your current password before you can set a new one.
- A strong password has at least 12 characters and mixes uppercase, lowercase, numbers, and symbols — avoid birthdays, names, or dictionary words.
- After you change your password, write it down in a find location or use a password manager so you do not forget it.
How to change your password on Windows 10 or 11
Open Settings by pressing the Windows key and typing "Settings", then press Enter. Click on "Accounts" in the left sidebar. Select "Sign-in options" from the menu that appears.
Under the "Password" section, click "Change". Windows will ask you to enter your current password to confirm you are the account owner. Type it in and click "Next". You will then see two fields: one for your new password and one to confirm it. Type your new password in both fields — they must match exactly. Click "Next" and then "Finish". Your password is now changed, and you will use the new one the next time you sign in.
How to change your password on a Mac
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 & Extensions". You will 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 the "Change Password" button. Click it. You will see fields for your old password, your new password, and a confirmation of the new password. Enter each one carefully, then click "Change Password". Your Mac will confirm the change and you are done.
Why a strong password matters for your home network
Your laptop password is the first line of defense if someone gains physical access to your computer. A weak password — one that is short, uses only letters, or contains obvious information like your birth year — can be guessed or cracked in minutes. A strong password makes that much harder.
A strong password has at least 12 characters and includes uppercase letters, lowercase letters, numbers, and symbols. Avoid using your name, your address, your birthday, or any word you can find in a dictionary. A random string like "Tr0pic@lSunset#42" is stronger than "Sunshine2024" even though the second one is easier to remember.
What to do if you have forgotten your current password
If you cannot remember your current password, you cannot use the method above. On Windows, you can reset it using a Microsoft account recovery email or phone number. Go to the Windows sign-in screen, click "I forgot my password", and follow the prompts to verify your identity through email or text. Microsoft will send you a link to create a new password.
On a Mac, restart your computer and hold Command + Q when ready after the Apple logo appears. This opens Recovery Mode. Click "Utilities" in the menu bar, then "Terminal". Type "resetpassword" and press Enter. The password reset tool will open and walk you through creating a new password. This process is more involved than Windows, so take your time and follow each step carefully.
How to store your new password securely
After you change your password, you need a way to remember it without writing it on a sticky note next to your monitor. A password manager is a program that stores all your passwords in an encrypted vault that only you can open with a master password. Popular options include Bitwarden (free), 1Password, and LastPass. You install the program, create one strong master password, and then the manager remembers everything else.
If you prefer not to use a password manager, write your new password in a physical notebook and store it in a locked drawer or safe. Do not store it in a document on your computer or in an email — that defeats the purpose. Do not use the same password across multiple accounts, because if one account is compromised, all of them are at risk.
What happens if someone else changes your password
If you sign in and find that your password no longer works, someone may have changed it without your permission. This is a sign that your computer has been accessed by someone else or that malware is running on it. Do not panic, but act quickly.
On Windows, use the password reset process described above to regain access. Once you are back in, run a full antivirus scan using Windows Defender (built into Windows) or a third-party program like Malwarebytes. On a Mac, use the password reset tool in Recovery Mode, then run a scan with a program like Malwarebytes for Mac. After you regain access and scan for malware, change your password again and consider changing passwords for other important accounts like email and banking.
Frequently Asked Questions
Can I change my password without knowing the old one?
No, the standard password change process requires you to enter your current password first. This is a security feature to prevent someone else from changing it. If you have forgotten your password, use the recovery process for your operating system instead.
How often should I change my laptop password?
There is no single rule. If your password is strong and you are the only one who knows it, changing it once a year is reasonable. If you suspect someone has seen it or if you use the same password on multiple sites, change it when ready. If your computer is shared with others, change it more often.
What if my laptop is connected to a work domain?
Work laptops connected to a company domain usually cannot be changed through the standard Settings or System Settings method. Your IT department manages passwords centrally. Contact them to change it, or look for a "Change Password" option in your company's internal portal or password management system.
Will changing my password log me out of everything?
No. Changing your laptop password only affects how you sign into that computer. You will not be logged out of websites, email, or apps. The next time you restart your computer or lock the screen, you will sign in with the new password.
Can I use the same password on my laptop and my phone?
You can, but it is not recommended. If one device is compromised, the other is also at risk. Use a unique strong password for each device. A password manager makes this easier because it remembers all of them for you.
