+### What is a Salt?
+A salt is a random value that is added to a password before hashing.
+
+It ensures that:
+- The same password does not produce the same hash every time
+- Precomputed attacks like rainbow tables become ineffective
+
+bcrypt automatically generates and stores the salt as part of the hash, so you do not need to manage it manually.
