I'm refurbishing laptops (Ubuntu 20.04) to hand out to kids as part of combating digital exclusion during COVID-19. Obviously I don't want to give them sudo access, however, I can't enter their houses to get onto WiFi.

How do I add a new connection when I set the laptop up (they can give me their SSID / passwords)?

I've tried

nmcli d wifi connect WiFi-SSID password 12345678

but that fails since the wifi isn't in range. I've tried

nmcli connection add type wifi ssid WIFI-SSID password 12345678

but that's throwing an invalid <setting>.<property> 'password'

Not sure where to go next...

read man nm-settings

a general example is

nmcli connection add type wifi con-name outofrange ssid HUAWEI 802-11-wireless-security.key-mgmt WPA-PSK 802-11-wireless-security.psk xxxxxxxx

the error in your question <setting>.<property> for example in above command,

<setting> 802-11-wireless-security <property> key-mgmt
<setting> 802-11-wireless-security <property> psk

Based on your OutOfRange connection settings change the above values..

You have to set all of options below in that order:

nmcli connection modify <ssid> wifi-sec.auth-alg open wifi-sec.key-mgmt wpa-psk wifi-sec.psk <password>
