Use platform guest features when available
Some ecosystems support limited home or lock access.
Physical fallback is still useful
Visitors should not be stranded because an app cannot be installed.
Set an end point
Temporary permissions should expire or be removed.
Never share owner recovery credentials
Account recovery codes and primary passwords are not guest-access tools.
Keep in mind. Compatibility is not permanent. Confirm the current manufacturer, platform and certification information before purchasing, resetting or migrating a device.
