Max WPA PSK is 63 characters but it isn't about days, it is about years. Honistly though, if someone wants on to your network that bad then it is most likely going to happen but I doubt it will be via a brute force attack, maybe an evil twin attack that tricks you into sending your PSK in clear text directly to the attacker or something along those sorts.
Yes you can use GPU accelerated attacks but against a 63 character PSK it is still going to take far too long to be practical. However, If you are worried that someone is going to crack your 63 character PSK then just change it every couple of years and you will be fine![]()


. And BTW why would someone want to hack you? What the heck do you have on your network? Banking information? Nuclear Missle launch codes? The secret of killing Chuck Norris?
