WordPress Salts: Enhancing Security & Encryption

WordPress Salts

WordPress salts are random cryptographic keys used to add an extra layer of security to your WordPress site. They are unique and complex strings of characters used in sensitive data encryption and hashing process, such as user passwords and authentication tokens.

Location of WordPress Salts


WordPress salts are located in your site’s wp-config.php file. This file contains various configurations for your WordPress installation, including the salts and keys used for encryption.

How WordPress Salts Work?

When a user enters their username and password to log into a WordPress site, the information is initially stored in two browser cookies and subsequently in the site’s database for future reference. However, storing passwords in plaintext poses a significant security risk, making them vulnerable to unauthorized access.

To address this concern, WordPress employs security keys and salts. Salts are random strings of characters generated by WordPress, unique to each installation. These salts are added to the user’s password before it is encrypted and stored in the database.

For example, let’s consider a password like “mypassword.” If WordPress were to store this password as is, it would be easily readable by anyone with access to the database. However, with salts, the password is transformed into a seemingly random and complex string like “hsd78q34%7832$4jkhkjsfd7878782^429nsdf” before being stored.

The purpose of salts is to add a layer of security by making it virtually impossible for anyone without access to the salts to decipher the original password from the stored string. It would be highly challenging to reverse-engineer the transformed password without the corresponding salts and security keys.

By employing salts, WordPress ensures that the stored passwords remain cryptographically protected even if a malicious actor gains unauthorized access to the database. The salts are an integral part of the encryption process, making it significantly more difficult for hackers to retrieve the original passwords.

WordPress salts are unique to each installation and are automatically generated during the WordPress installation process. They are securely stored in the wp-config.php file, ensuring only authorized individuals can access them.

Why Should You Change Your Security Keys and WP Salts?

Changing your WordPress security keys and salts regularly is a recommended practice to enhance the security of your WordPress website. Here are some reasons why you should consider changing them:

Improved Security 

By changing your security keys and salts periodically, you add an extra layer of security to your WordPress site. This helps to safeguard sensitive information and protect against potential security breaches.

Automatic Logout

When you change the security keys and salts, all logged-in users will be automatically logged out. This is particularly beneficial if you frequently access your WordPress site from multiple devices or browsers. Changing the keys ensures unauthorized access to your login details is immediately invalidated.

Restricting Unauthorized Access

Changing your security keys and salts helps to prevent unauthorized access to your site’s back-end. Modifying the salts and passwords effectively locks out any hackers who may have gained access to your previous keys.

How To Change WordPress Salts (Two Methods)

If you wish to change salts in WordPress, two primary methods are available: manual editing of the wp-config.php file or using a plugin. Let’s explore both approaches in detail:

Changing WordPress Salts Manually:


To change your WordPress salts, you can follow these steps:

  1. Access your WordPress site’s wp-config.php file, usually in your site’s root directory.
  2. Open the file using a text editor.
  3. Look for the section that contains the salts and keys. It should be labeled with comments mentioning “Authentication Unique Keys and Salts.”
  4. Generate new salts using a reliable online generator or a security plugin.
  5. Replace the existing salts with the newly generated ones.
  6. Save the wp-config.php file.

By changing your WordPress salts regularly, you ensure that even if someone gains unauthorized access to your database, the encrypted data will remain extremely difficult to decrypt. This adds an extra layer of protection to your WordPress site and helps safeguard sensitive user information.
