A technique allows software developers to develop applications for a smart phone or other terminal by unlocking the terminal so that it can run unsigned applications. A developer registers with a web-based service, agrees to registration terms, and provides authentication credentials. Data which verifies the authentication credentials is provided back to the developer's computer. The terminal is connected to the developer's computer, and via a user interface, the developer requests registration of the terminal. In response, the terminal receives the data from the developer's computer, and provides the data and a unique terminal identifier to the service. If authorized, the service returns a persistent token or license which is stored at, and used to unlock, the terminal. The service can also provide a command which enforces an expiration date. The terminal checks in with the service to determine if the account is in good standing, and is re-locked if warranted.
