Definition
A security technology where the remote and opener generate a new code from a shared algorithm every time you press the button, so a thief with a code-grabbing device cannot record and replay your signal. Virtually every opener made since the mid-1990s uses it — LiftMaster's version is branded Security+. If your opener is old enough to use a fixed code, often set by little DIP switches inside the remote, it is genuinely easy to clone, and that alone is a good reason to upgrade.
