from what I'm reading online it seems that one can land attacks and successfully crack a WPA2-PSK wifi network, is that true and if it is, how home users can secure their networks? I seen an application on android that can reveal the wifi password even with WPA2 and it was not a trick.

I know that there is a vulnerability with WPS, even when using WPA2, but aside from that is WPA2-PSK really secure?
