What is password salting?

Password salting is a security technique used to enhance the protection of hashed passwords by adding a unique string, or "salt," to each password before it is hashed, making it more difficult for attackers to decipher in the event of a data breach. This method deters rainbow table attacks, which rely on pre-computed lists of password hashes, by ensuring that identical passwords result in different hashed values due to the unique salt. The concept is distinct from "peppering," which involves adding a random value stored separately from the hashed password, increasing security but also computational load. Best practices for salting include using unique, randomly generated strings for each password and ensuring the salt length matches the hash output to maximize security. Stytch's Passwords solution incorporates these best practices with the advanced Scrypt hashing algorithm and offers additional security features like breach detection and password strength assessment, while also exploring passwordless authentication options for enhanced security.
