Your network username and password are what you use to log into your computer when it starts.
Username: LastName+FirstInitial i.e.: SmithJ
Password: Passphrase of at least 14 characters. Try to make it a phrase that is easy for you to remember and it cannot be the same as your previous 3 passwords
Passwords expire every 365 days
Be aware that after 5 failed attempts the system will lock your account.
Also, remember that your Microsoft 365 ID for all Microsoft sites (SharePoint, OneDrive, Office.com etc...) is your username plus "@theaiedge.com" and the password for those sites is the same as your network password.
