Hash functions are commonly used for saving passwords. When a user creates a password, it gets hashed and stored in a database. When the user logs in, the entered password gets hashed and compared to the stored hash. If they match, access is granted. This ensures that even if a hacker gains access to the database, they won't be able to see the actual passwords.
