with the new emonSD image the wifi-AP is no longer secured with a password, as it is still written in the manual (https://guide.openenergymonitor.org/setup/connect/). Is this intended? The file
/etc/hostapd/hostapd.conf only contains the configuration without authentication.
For all others, who would like to set a password, here is very well documented how this works: https://github.com/openenergymonitor/emonpi/blob/master/wifiAP/readme.md
