In short: A supervision lock is the ability to control a mobile device through MDM supervision — a special management state that gives an organization deeper control over a device it owns or leases. It is the technology behind "supervision lock" in phone rental.
In Apple's ecosystem, a device can be either supervised or unsupervised. A supervised device is owned and managed by an organization. Supervised devices accept management commands that unsupervised devices do not, such as remote lock, app restrictions and activation lock management.
For a phone rental business, supervision lock means the rental platform — not the customer — ultimately controls the device. When a contract is breached, the platform can restrict the device through official channels. It is a compliance-safe alternative to third-party locks that rely on jailbreaks.
A supervision lock runs on Apple's official MDM framework, keeps working across iOS updates, and provides an auditable control path. A jailbreak-based "lock" is fragile, non-compliant and breaks with system updates. This is the single most important distinction when choosing a provider.
