WPA and WPA2 can be cracked with Aircrack. Kali Linux includes the Aircrack suite, which is one of the most popular applications to break wireless security. Aircrack works by gathering packets seen on a wireless connection to either mathematically analyze the data to crack weaker protocols such as Wired Equivalent Privacy (WEP), or use brute force on the captured data with a wordlist.

Cracking WPA/WPA2 can be done due to a weakness in the four-way handshake between the client and the access point. In summary, a client will authenticate to an access point and go through a four-step process.
