Change PW for a network

[blockie]

I live in an Assisted Care facility and get WIFI as part of the rent.I am used to entering a password to activate the ability to get WIFI. I have heard this security code called password or passphrase. Now, to get on this facility's network I am offered "voucher codes" to place in the box where I usually put a password. I suspect a "voucher code" is just another name for passphrase/password. Am I correct? Please explain?

I want to change the "pw" that I have been using, putting in one of the "voucher codes" that the management of this facility gave to me. But, I don't know how because the option box that I would usually
use is no longer visible since I checked the automatic logon box. There must be another way. Can a network have more than one PW, PP or voucher code or whatever it may be called? Please advise.

You need to forget the existing WiFi connection (usually done via Manage Wireless Connections) then make a new connection. When you do that you can then enter the new password.
