What is my "Network password"?
MUSD users have two primary credentials (combination of a username and a password) that are used to access MUSD systems. One is for the network and the other is for Google. Your Network credentials are used to log in to network services like admin wireless, servers, network printers, and Windows PCs (and in 2020, new MacBook laptops). Typically your network username is your first initial followed by your last name (the first part of your email address) and an network password. Your Google username is your email address and Google password.
Here is an example:
User John Doe. His network username is jdoe. His Google username (email) would be jdoe@musd.org. Each would have their own password (you could set them to be the same if you choose).
MUSD users can change their password for each system as desired or required. To change the network password, follow the instructions below. For Google, visit account.google.com and change your password there under the "Security" section.
Password self service system
Open an Internet browser and go to password.musd.org.
If you remember your Network password use the "Change Password" section to enter your current user name and password. You will then be prompted to enter a new password.
If you have forgotten your Network password, use the "Reset Password" section. Clicking on this section will bring up another screen prompting for your user name and then a captcha to verify that you are human.
On the next screen, select your email address from the drop down and enter another captcha, then click Continue. The system will then send an email to the MUSD email address in our system that includes a link you click on to reset your password.
Special Considerations for Older Macs
Those of you with older Apple Mac laptops (before 2020) will need to make some additional changes to your system after changing your Network password. This is due to the way that the Macs interface with our systems. Specifically you will need to enter your new Network password to connect to the wireless network and network printers. Here is what you will need to do.
Once you have changed your Network password, you will have to reconfigure your wireless network connection to use the new password.
Log in to your Mac (remember that the password for your Mac login has not been changed, we have only changed your Network password).
On the menu bar (across the top of the screen) click on the AirPort symbol (it may look like the pic above or like one of these:
In the AirPort drop down menu, Click on the “MUSDWireless” network. This should show up in the list if it was previously setup on your Mac. If you do not see MUSDWireless in the list, please call Technology Services at x6008 for assistance.
On the password box, enter your new password and make sure that the box next to “Remember this information” is checked, then click “OK”.
Your wireless connection should now be connected. If not, please call Technology services at x6008 for assistance.
Now you will need to reconnect to your network printer(s).
If you haven’t sent a print job to the printer, do so now by printing something.
Go to the Apple icon at the top left of the screen, select “System Preferences...”.
On the System Preferences screen, select the option “Printers & Scanners”.
On the Printers & Scanners screen, select the network printer you sent a print job to by clicking on it. Once the printer is highlighted, click on “Open Print Queue…” button.
The Print Queue screen will pop up with a list of the job or jobs you were trying to print. Click the on the re-print button 
An authentication window for the printer should pop up prompting for your network username and password. Enter your user name and new network password and ensure the “Remember this password in my keychain” checkbox is checked (otherwise you will have to enter your credentials every time you need to print).
If you have more than one network printer installed, your network credentials only need to be entered for one of the printers - you should not need to enter them for any of the other printers.
In the process of the above changes, you may get a popup window with a lock icon similar to this one:
This is the administrative lock system used on Macs to prevent accidental changes to your system. When Technology Services originally sets up your Mac, we enter your username and the password “musd” for this account. It is not affected by your Network or Google password changes and is only used as part of the administrative lock system on the Mac.
