Cracking WPA is definitely possible, but it takes a little bit of time and patience. There are two main methods for cracking WPA: dictionary attacks and brute-force attacks.
Dictionary attacks are the most common method used to crack WPA. This method involves using a pre-generated list of common words and phrases (known as a dictionary) to try and guess the password. If the password is in the dictionary, then it will eventually be cracked. However, if the password is not in the dictionary, then this method will not work.
Brute-force attacks are less common, but they can be more effective than dictionary attacks. This method involves trying every single possible combination of characters until the correct password is found. Obviously, this can take a very long time depending on how complex the password is. But if you have enough time and computing power, then brute-force attacks will eventually crack any password.
