WordPress plugins are essential for improving a website’s functionality, however, many premium plugins require a valid license for continuous updates and support. These licensing keys are often kept in the WordPress database, allowing the plugin to check its legality. Managing plugin licensing correctly is critical for ensuring website security, functionality, and compliance with plugin providers’ terms of service.

Failure to properly handle plugin licensing can result in expired plugins, missing security patches, and even malfunctioning website functionalities. This post will look at how WordPress maintains plugin licenses, typical concerns with their storage, and best practices for maintaining them safely.

How WordPress Plugin Licenses Are Stored in Databases?

WordPress retains plugin license keys in its database, specifically the wp_options table. Typically, license keys are saved as key-value pairs in the wp_options table’s option_name and option_value columns. The structure of this storage method varies depending on the plugin developer, however common naming standards for license keys include:

- plugin_name_license_key
- plugin_name_license_status
- plugin_name_api_key

If you have a premium plugin called ‘MyCustomPlugin’, its licensing key may be stored as: option_name: mycustomplugin_license_keyoption_value.

Common Issues With Storing WordPress Plugin Licenses

Though keeping plugin licensing in a database is convenient, many difficulties may arise:

Turn Clicks Into Automation Magic

1. Expired licenses

When a plugin’s license expires, it frequently no longer receives updates or support.
Users may not receive alerts of expiring licenses, resulting in outdated software.

2. Missing or corrupted database entries

If a site migration or database restoration is not completed properly, license keys may be lost or corrupted.
Some plugins fail to update their licensing key entries correctly, resulting in activation issues.

3. Incorrect storage format

Some plugins save license keys in serialized arrays, which makes manual retrieval more difficult.
Users who attempt to manually modify or update licenses risk corrupting the stored data.

4. Security Risks

License keys saved in plain text are vulnerable to unauthorized access, and poor database security procedures might expose important plugin data.

How to Find and Maintain Plugin License Keys in WordPress

To identify or change your WordPress plugin license key, follow these steps:

1. Access the WordPress database.
  To access your website’s database, use phpMyAdmin (or any other MySQL management tool).
2. Locate the i table.
  Open phpMyAdmin and navigate to the wp_options table.
3. Search for the license key.
  Run a SQL query to find license-related entries:
  SELECT * FROM wp_options WHERE option_name LIKE ‘%license%’; Find keys with option names like plugin_name_license_key.
4. Change or Update the License Key.
  If you need to alter a key, change the option_value field accordingly.
  To avoid issues, ensure that the key is formatted appropriately.

Best Practices for Securely Storing WordPress Plugin License Keys

Follow these easy steps to ensure the security and integrity of your plugin licensing keys:

- Avoid storing license keys in plain text. Protect sensitive information with encryption techniques.
- Back up your database regularly. Keep a backup of the database in case it gets corrupted or accidentally removed.
- Install safe database access controls. Limit access to the WordPress database to avoid unauthorized changes.
- Don’t hardcode licensing keys into files. Hardcoding keys in wp-config.php or theme files make them vulnerable to attacks.
- Keep Plugins and WordPress Updated: Outdated plugins might cause security risks.

Troubleshooting and Solutions for Plugin Issues

If you have problems with plugin licenses, try the following troubleshooting steps:

1. License key not recognized
  Ensure that the key is accurately inserted into the wp_options table.
  Check that the plugin is correctly installed and active.
2. Expired Licence Issues
  Renew your license at the plugin provider’s official website.
  Check that the updated key is reflected in the database.
3. Database Corruption
  Restore the database from a backup.
  Reinstall the affected plugin and reactivate your license.
4. The plugin is still not accepting the license
  Please contact the plugin supplier for verification.
  Check for any problems with other plugins or themes.
