Where your username and password actually live on your computer

Your computer username is stored in your operating system settings, not in a single file you can open. Windows and Mac keep it in different places, and the steps to find it take less than a minute. Your password is intentionally harder to access — the system stores an encrypted version, not the actual characters you typed — so you cannot straightforward look it up the way you would find a username.

If you have forgotten your password, you will need to reset it rather than retrieve it. If you remember your password but want to change it to something new, that is a separate process. Both are straightforward, but they work differently depending on whether you use a local account or a Microsoft/Apple account.

Key Takeaways

  • Your username appears in Settings on Windows or System Preferences on Mac, and you can find it in under one minute without any special tools.
  • Passwords are encrypted and cannot be retrieved — if you have forgotten yours, you will need to reset it using your security questions or recovery email.
  • Windows stores passwords for websites and apps separately from your login password, and you can view those in Credential Manager if you need to confirm what you saved.
  • If you are locked out of your account entirely, you will need access to a recovery email address or phone number you set up beforehand.

Finding your username on Windows

Open Settings by pressing the Windows key and typing "Settings," then click the app that appears. Go to Accounts on the left side, then click Your info. Your username appears at the top under your profile picture. This is the name you type when you log in.

If you see an email address instead of a username, you are using a Microsoft account rather than a local account. Both work the same way for logging in — you just type the email address instead of a short name. The email address is your username in this case.

Finding your username on Mac

Click the Apple menu in the top-left corner and select System Preferences (or System Settings on newer versions). Go to Users & Groups or General depending on your macOS version. Your username appears under the account name. On Mac, this is sometimes called your "short name" and is different from your full display name.

If you are not sure which account you are using, look for a lock icon in the bottom-left corner of the Users & Groups window. Click it and enter your password to make changes. Your account name is listed on the left side of the window.

What to do if you have forgotten your password

You cannot retrieve a forgotten password because your computer stores only an encrypted version of it. Instead, you reset it. On Windows, go to Settings > Accounts > Your info and click Manage your Microsoft account (if you use a Microsoft account) or Change your password (if you use a local account). You will be asked to verify your identity using a recovery email or phone number.

On Mac, restart your computer and hold Command + Q when you see the login screen. This opens the reset password utility. Select your account and answer your security questions, or use your recovery key if you saved one. You can then create a new password.

If you do not remember your security questions or no longer have access to your recovery email, the process becomes much longer. You may need to contact Microsoft support (for Windows) or Apple support (for Mac) with proof of ownership. This is why setting up a recovery email and phone number when you first create your account matters.

Finding passwords you have saved in your browser or Windows

Passwords you save for websites live separately from your login password. On Windows, open Credential Manager by pressing the Windows key and typing "Credential Manager." Click Web Credentials to see websites where you saved passwords. Click any entry to reveal the password (you will need to enter your Windows password first).

In most web browsers, you can also view saved passwords directly. In Chrome, go to Settings > Passwords. In Firefox, go to Settings > Privacy & Security > Passwords. In Safari on Mac, go to Preferences > Passwords. Each browser will ask you to authenticate before showing the actual password.

Be cautious about viewing saved passwords on a shared computer. Anyone with access to your account can see them once they are revealed.

Changing your password to something new

On Windows with a Microsoft account, go to Settings > Accounts > Your info and click Manage your Microsoft account. Select Security and then Change password. You will enter your current password, then type your new password twice.

On Windows with a local account, go to Settings > Accounts > Sign-in options and click Password > Change. Enter your current password, then your new password twice.

On Mac, go to System Preferences > Users & Groups, click the lock icon to unlock it, select your account, and click Change Password. Enter your old password, then your new password twice.

What happens if you are locked out completely

If you cannot remember your password and do not have access to your recovery email or phone, you will need to prove you own the computer. On Windows, Microsoft will ask you to verify your identity through a recovery code or by answering security questions you set up earlier. If you have none of these, you may need to contact support with proof of purchase.

On Mac, you can use your Apple ID to reset your password if you set that option up beforehand. If not, you will need to use your recovery key (a long code Apple gave you when you created your account) or contact Apple support. Without any of these, you may need to erase your drive and reinstall the operating system, which will delete your files.

Frequently Asked Questions

Can I see my password after I have typed it in?

No. Once you log in, your password is encrypted and stored in a way that even your computer cannot read back. This is intentional — it protects you if someone gains access to your computer's files. You can only reset your password, not retrieve it.

What is the difference between my username and my email address?

If you use a local account, your username is a short name you created (like "sarah" or "john123"). If you use a Microsoft or Apple account, your email address is your username. Both work the same way when you log in — you just type whichever one your account uses.

Is it safe to save passwords in my browser?

Browser password storage is reasonably safe if your computer is password-protected and you are the only person who uses it. Anyone with access to your account can view those passwords once they log in. On a shared computer, it is safer to use a password manager instead, which encrypts passwords separately.

What if I see a username I do not recognize on my computer?

Your computer may have multiple user accounts. Go to Settings > Accounts > Other people (Windows) or System Preferences > Users & Groups (Mac) to see all accounts. If you see an account you did not create, check with others who use the computer. If you are the only user, contact your computer manufacturer or IT support.

Can I change my username without losing my files?

On Windows and Mac, you can change your display name without affecting your files. However, changing your actual account name (the short name) is more complex and may affect file permissions. It is usually safer to create a new account and transfer files over, or contact support before attempting to rename your account.
