## What is **Salt**?

**Salt** — A random value made for each user and mixed into their password before it's hashed, then stored beside the hash. Two people with the same password get different hashes, so an attacker can't look them up in a table of known hashes.

## In a sentence

- “Each user gets their own **salt**, so two people with the password "chai123" have different hashes.”
