You should probably have some safeguard to prevent jokers from uploading 14.2 gigabytes of absolute nonsense into your system's password field just to see if they can make it crash. But I think limiting it to, like, 8 kB ought to be quite lenient for anything with a modern internet connection.

As others have noticed, various hashing functions have an upperbound input length limit anyway. But I don't see any pressing reason to limit your field length to exactly that, even if only not to reveal anything about what you might be feeding that value into behind the scenes.
