    Hello BARBARA PEARSON,

    From your description, it sounds like you're trying to update your Brother HL-L2405W printer rather than Windows itself.

    Brother confirms that its firmware update tool may request the printer's administrator password, which is different from your Wi-Fi or Windows password.

    If that's the screen you're seeing:

    1. Check the back or bottom of your Brother printer for a label marked Pwd.
    2. Enter the 8-character password shown there, paying attention to uppercase and lowercase letters.
    3. If you've previously changed the printer's administrator password, you'll need to use the changed password instead.

    Brother's official instructions:

    However, you also mentioned seeing a Wi-Fi passcode screen. If the password above doesn't apply, could you share a screenshot of the screen asking for the password? Please hide any passwords or personal information.

    That should help us identify which password is actually required.

    Enter the password for a Windows administrator account—the prompt is from Windows User Account Control (UAC), not from the Brother HL-L2405W, so the printer’s passcode and a Windows Hello PIN will not satisfy it.

    What to enter

    1. Check the account name or email displayed in the UAC window.
    2. Enter the password for that Windows administrator account.
      • If it displays an email address, use that Microsoft account’s password.
      • If it displays a local username, use that local Windows account’s password.
    3. If More choices appears, select it and choose a different administrator account.

    A standard Windows user receives a credential prompt when an operation needs administrative access; Windows requires a valid administrator username and password to continue.^1^

    If the password is forgotten

    • Microsoft account: Reset its password using Forgotten your password?, verify the account with a security code, and create a new password.^2^
    • Local Windows account: At the Windows sign-in screen, select the arrow beside the password field, then OK → Reset password, and answer the account’s security questions.^3^

    After resetting it, sign out or restart Windows, sign in with the new password once, and then run Windows Update again.

    If the PC belongs to your brother or his account is the only administrator, he must enter or recover that Windows administrator password. A printer password cannot grant Windows administrator permission, and the password should not be bypassed.
