Modifying security state with secured range detection

A device comprising:

• a memory;
• and
• at least one processor configured to:
• detect an announced availability of a second device for modifying a security state at the device;
• exchange, using a first wireless protocol, ranging connection information with the second device;
• perform, using a second wireless protocol and based on the ranging connection information, a ranging operation with the second device to estimate a distance between the device and the second device;
• and
• in response to a determination that the distance satisfies a distance threshold, establish, using the first wireless protocol, a connection with the second device for modifying the security state at the device.

A non-transitory machine-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• detecting an announced availability of a second device for modifying a security state at a first device;
• exchanging, using a first wireless protocol, ranging connection information with the second device;
• performing, using a second wireless protocol and based on the ranging connection information, a ranging operation with the second device to estimate a distance between the first and second devices;
• and
• in response to a determination that the distance satisfies a distance threshold, establishing, using the first wireless protocol, a connection with the second device for modifying the security state at the first device.
