Does the use of a salt increase password security Why or why

Does the use of a salt increase password security? Why or why not?

Solution

Yes. Salt do increase the password security. Assume a multiple users have the same password. And the passwords are securely hashed. But without salt, the hash values for both the passwords seems to be the same. Which means, if one password is cracked, then you can check for similar hashes, and you have access to all the accounts that use the same password. Whereas, if the passwords are salted, which means every hash is uniquely randomized so that even if the passwords are same, the salted hashes appear different from one another. Ofcourse, its not impossible to crack the salted hashes, but it will be a lot more harder than the one compared to unsalted hashing.
