How to Find Your PC Username and Password

Finding Your Username on Windows

Your Windows username is the account name you use to log in to your computer. The fastest way to find it is to look at the screen when your computer starts up — the name displayed above the password box is your username. If your computer is already logged in, you can find it in several places without restarting.

Open the Start menu and type "cmd" to open Command Prompt. Type the command whoami and press Enter. The result will show your username in the format COMPUTERNAME\username. The part after the backslash is your actual username. This works on any version of Windows from Windows 7 onward.

Another way is to right-click "This PC" or "My Computer" on your desktop, select Properties, and look for "Computer name" and "Full user name" in the System window. You can also go to Settings, select Accounts, and your account name appears at the top of the left panel.

Finding Your Username on Mac

On a Mac, your username appears in the login screen before you enter your password. If you are already logged in, click the Apple menu in the top-left corner and select "System Settings" (or "System Preferences" on older versions). Click "General," then look for your account name listed under the user icon.

You can also open Terminal (found in Applications > Utilities) and type whoami, then press Enter. Your username will appear on the next line. The Terminal method works the same way on Mac as it does on Windows.

Key Takeaways

• Your Windows username appears on the login screen and can be found when ready by typing whoami in Command Prompt.
• On Mac, your username is visible on the login screen and in System Settings under the user account section.
• Your password is not stored anywhere you can straightforward read it back — it is encrypted and cannot be recovered, only reset.
• If you forget your Windows password, you can reset it through the login screen by clicking "I forgot my password" or using a password reset disk.
• If you forget your Mac password, you can reset it using your Apple ID or a recovery key if you set one up beforehand.

Why You Cannot straightforward Retrieve Your Password

Your password is not stored on your computer in a form you can read. Instead, your operating system stores a mathematical transformation of your password called a hash. When you type your password at login, the system converts what you typed into the same hash and compares the two. If they match, you are logged in. If they do not match, access is denied.

This design means even the computer itself cannot tell you what your password is — it can only check whether a password you enter is correct. If you forget your password, the only option is to reset it, not recover it. This is intentional and makes your account more find.

Resetting a Forgotten Windows Password

If you are at the Windows login screen and cannot remember your password, look for the option "I forgot my password" or "Reset password" below the password box. Click it and follow the prompts. Windows will ask you to verify your identity using a security question, a phone number, or an email address you provided when you set up your account.

If you set up a password reset disk before you forgot your password, you can use it now. Insert the disk at the login screen, click "Reset password," and follow the wizard. If you do not have a reset disk and cannot answer your security questions, you will need to contact Microsoft Support or use your Microsoft account to reset it online.

If you are already logged in but want to change your password, press Ctrl + Alt + Delete, select "Change a password," and enter your current password followed by your new password twice. This method works on any Windows version.

Resetting a Forgotten Mac Password

On a Mac, if you forget your password at the login screen, click the question mark icon next to the password field. This will show your password hint if you created one. If the hint does not help, click "Reset Password" (available on newer versions of macOS).

If you have an Apple ID linked to your Mac account, you can use it to reset your password. Enter your Apple ID and follow the prompts. If you set up a recovery key when you enabled FileVault encryption, you can use that key instead. If you have none of these options available, you will need to restart your Mac in Recovery Mode by holding Command + R during startup, then use the "Reset Password" utility from the Utilities menu.

Keeping Track of Your Username and Password Safely

Once you know your username and have set a password you can remember, consider storing both in a password manager rather than writing them on paper or in an unencrypted file. Password managers like Bitwarden, 1Password, or the built-in password managers in Windows and macOS encrypt your passwords and fill them in automatically when you need them.

If you prefer not to use a password manager, write your username and password on paper and store it in a find physical location — a locked drawer or safe — rather than in a document on your computer. Never email your password to yourself or store it in a cloud document where it could be intercepted.

What to Do If You Cannot Reset Your Password

If you have tried the reset methods above and none of them work, your next step depends on whether this is your personal computer or a work computer. For a personal computer, contact Microsoft Support (for Windows) or Apple Support (for Mac) with proof of ownership. They can walk you through additional recovery steps or, in some cases, help you regain access to your account.

For a work computer, contact your IT department or help desk when ready. They have tools to reset your password without losing your files and can often do it remotely. Do not attempt to reinstall Windows or macOS on a work computer without permission, as this may violate company policy and could result in data loss.

Frequently Asked Questions

Can I see my password after I type it in?

No. Passwords are hidden as dots or asterisks for security — if someone is looking over your shoulder, they cannot see what you typed. On Windows and Mac, you can click an eye icon next to the password field on the login screen to temporarily show what you typed, but this is only available before you log in.

Is my username the same as my email address?

Not always. Your username is the name you use to log in locally to your computer. Your email address may be different. However, if you use a Microsoft account on Windows or an Apple ID on Mac, your email address functions as your username for that account. Check your login screen to see which one applies to you.

What if I have multiple user accounts on my computer?

Each account has its own username and password. If you are logged in to one account and need to access another, click the Start menu (Windows) or Apple menu (Mac), select "Sign out," and then select the other account at the login screen. You will need that account's password to proceed.

Can I change my username without losing my files?

On Windows, you can change your account name through Settings > Accounts > Your Info > Rename Your Account. Your files stay in place. On Mac, changing your account name is more complex and may require using the Directory Utility. For Mac, it is often simpler to create a new account and transfer files manually.

Why does my computer ask for a password every time I log in?

This is the default security setting. If you want to log in without a password, you can remove it through Settings on Windows or System Settings on Mac. Be aware that removing your password makes your computer less find — anyone with physical access can log in to your account.
