Is the MySQL PASSWORD Function Still Suitable for Password Hashing?

Should the MySQL PASSWORD Function Be Used for Password Hashing?

The MySQL PASSWORD function is commonly used for authentication within MySQL Server, but its usage in application password hashing is a subject of debate.

MySQL's Recommendation

The official MySQL documentation explicitly discourages the use of the PASSWORD function outside of authentication within the server. It suggests consulting external resources for more appropriate password hashing practices.

Alternatives to MySQL PASSWORD

Experts recommend using more robust hashing algorithms, such as SHA-256, to secure passwords. While MD5 and SHA-1 were once widely used, they have been deemed too weak.

Implement Hashing in Your Language

Instead of relying on the MySQL PASSWORD function, it is advisable to implement hashing and salting within your application's programming language. This allows you to employ more secure algorithms and maintain control over the process.

Use SHA2 Function (MySQL 5.5.8 and Later)

In MySQL 5.5.8 and later, the SHA2 function was introduced. This provides support for the SHA-256 algorithm, making it an alternative to using hashing in your application's code.

Deprecation in MySQL 8.0

With the release of MySQL 8.0, the PASSWORD function was removed, reinforcing the recommendation to utilize other methods for password hashing in applications.
