Wifi with WPA2-EAP MS-CHAPv2 authentication (username and password) during Debian installation

I am currently attempting to install Debian on my laptop computer. During the network configuration stage, I am prompted to "enter a passphrase for WPA/WPA2 PSK authentication". Unfortunately, I am on my school's network which requires both a username and a password, with the [MS-CHAPv2](https://en.wikipedia.org/wiki/Wi-Fi_Protected_Access#MS-CHAPv2) authentication protocol. What should I enter at the prompt? I have an Ubuntu computer which can connect to this network. Here are the contents of /etc/NetworkManager/system-connections/NetworkName: [ipv6] method=auto [connection] id=NetworkName uuid=3e728a68-a877-4681-bc0e-1e64b2ff6434 type=802-11-wireless [802-11-wireless-security] key-mgmt=wpa-eap auth-alg=open [802-11-wireless] ssid=NetworkName mode=infrastructure mac-address=84:A6:C8:A9:67:DA security=802-11-wireless-security [802-1x] eap=ttls; identity=username phase2-auth=mschapv2 password-flags=1 [ipv4] method=auto Curiously enough, the password I enter to connect to NetworkName doesn't appear anywhere.
