The secret keys in WordPress are used to enhance the security of your website. They are a set of random variables that are used in conjunction with cookies and other security measures to ensure that data transmitted between your website and your visitors’ browsers is secure.
When you generate new secret keys, you are essentially creating new and unique values that are used to encrypt and decrypt information that is stored in cookies and other data storage mechanisms. This helps to ensure that even if someone were to gain access to the data stored in a cookie, they would not be able to read or interpret it without the secret keys that were used to encrypt it.
In addition to enhancing security, regenerating secret keys can also be useful if you suspect that your site’s security has been compromised. By generating new secret keys, you can effectively invalidate any existing cookies or other data that may have been obtained by an attacker, making it more difficult for them to continue accessing your site.
To generate new secret keys in WordPress, you can use a plugin such as the Secure Security Keys plugin or you can manually add new keys to your site’s wp-config.php file. Before making any changes to your site, it’s always a good idea to back up your site to ensure that you can easily revert to a previous version if necessary.
