Connect to a wifi that requires a username

I am new to the BBB and Debian, but I have successfully connected my BBB to my wifi at home, and I would now like to connect to the wifi at school, but the wifi requires a username and password. I can’t find instructions on adding a username to the “/etc/network/interfaces” file. Is this possible? Any help would be appreciated.

In /etc/network/interfaces there is already a "WiFi Example"
