Glpi Registration Key Work -

Q: Can I use one key on multiple GLPI instances?
A: No. Most keys are locked to a single instance (by domain or unique installation ID). Cloud subscriptions are per organization.

Q: What happens if my key expires?
A: Premium features stop working or revert to read-only mode. Support access ends. The Community Edition base remains functional.

Q: Is there a free trial key?
A: Yes, many vendors offer 15- or 30-day trial keys for plugins or the Enterprise subscription.

Q: Do I need a key for GLPI open-source plugins?
A: No. Only commercial plugins require registration keys.

To illustrate exactly how a GLPI registration key works in a real scenario, let’s walk through a common example: glpi registration key work

Context: You have purchased FusionInventory for GLPI (Enterprise version) with a 200-device license.

You need a class in your plugin, for example, PluginMyregistrationKey, to handle the logic.

1. Generating the Key: Create a method to generate a secure random string and save it to the database.

class PluginMyregistrationKey extends CommonDBTM 
public static function generateRegistrationKey($params) 
    global $DB;
// Generate a secure random token
    $token = bin2hex(random_bytes(16));
$input = [
        'name'           => $params['name'],
        'registration_key' => $token,
        'is_active'      => 1,
        'expiration_date'=> $params['expiration_date'],
        'entities_id'    => $params['entities_id'],
        'profiles_id'    => $params['profiles_id'], // Usually 'Self-Service'
        'date_creation'  => $_SESSION['glpi_currenttime'],
    ];
return $DB->insert('glpi_plugin_myregistration_keys', $input);
public static function getRegistrationURL($key) 
    // Returns the public-facing URL
    return GLPI_URI . 'index.php?registration_key=' . $key;

"Registration key work" often translates to troubleshooting why a valid key is not being accepted. The failure points generally fall into three categories:

Connectivity Issues The most common cause of registration failure is the server’s inability to reach the vendor's validation servers.

Key Integrity Copy-paste errors are frequent. Keys often contain complex strings that can be truncated or altered if copied from an email client with formatting issues. Q: Can I use one key on multiple GLPI instances

Server Time Drift Registration keys validate the "current date" against the "expiration date." If the GLPI server’s system time is incorrect—whether due to a drained CMOS battery or an out-of-sync NTP (Network Time Protocol) service—the validation logic may fail. If the server thinks it is the year 2030, a key valid for 2024 will be rejected as expired.

The Goal: Create a system where an Admin can generate a unique key. This key is embedded in a URL. When a new user clicks the URL, they are presented with a registration form. Upon successful submission, a GLPI user account is created.
