Where Does MySQL Store Passwords? Explained

When it comes to MySQL, one common question that many users have is: 'Where does MySQL store passwords?'

In MySQL, user account information, including passwords, is stored in the 'mysql.user' table. This table contains details such as username, password, host, and privileges associated with each user account.

It is crucial to understand that MySQL stores passwords using cryptographic hashing techniques for security reasons. Instead of storing plain text passwords, MySQL stores password hashes, which are irreversible and provide an added layer of protection.

When a user attempts to log in, MySQL takes the entered password, hashes it using the same algorithm, and compares it with the stored hash in the 'mysql.user' table. If the hashes match, access is granted; otherwise, the login is denied.

Ensuring the security of password storage is essential in any database management system to prevent unauthorized access and protect sensitive information.
