Automatic Activation: Once signed in, the server automatically detects your plan (e.g., Lite, Essentials, or Plus) and applies the license. 2. Legacy and Offline License Keys
If you are using an older version or an environment without internet access, you may still require a 25-character license key.
Finding Offline Keys: You can find these details on the Deployment page of your RealVNC account portal.
