Passwords can be passed to NM as part of the initial connection that you pass to the AddConnection(). But I think it would be great to have this more embedded in NetworkManager instead, which would work with all clients not just nmcli. Here's an idea; possibly not the best one. In wifi_secrets_cb() we can figure out if this is the first time the connection has been used with nm_settings_connection_get_timestamp(). If timestamp is 0, and there are no secrets, then we could check whether the AP has WPS IEs that we can use. If so, we could call nm_act_request_get_secrets(wifi_wps_secrets_cb) and pass a hint (like "x-nm-wps-methods=<ssid>,pbc,pin" that clients could use to display an alert that says "Please push the WPS button on the access point or enter the PIN code for the network <ssid>". If PBC then I don't think we need to return any secrets, if PIN then we could just stuff the PIN into the PSK secret. Once the user has done that and hit "OK" the request would come back to NetworkManager into a wifi_wps_secrets_cb(). If the request wasn't canceled, assume that the AP is now available for WPS, and continue with the connection but instead of sending the full config to the supplicant NM would initiate WPS instead. Once the the supplicant has figured out the actual PSK, we'd grab that from the network block and save that in the NM config.
