    Assigning permanent passwords When you log in for the first time, Extreme Networks recommends that you change the passwords for the default accounts. The factory-configured default accounts are admin, user, and root. Use the default administrative account as shown in the following table to log in to the device for the first time and to perform the basic configuration tasks.
