7. The method of claim 1 , further comprising:

providing the first number to the messaging service; and

retrieving the first number from the messaging service further based on authentication of the remote device.

8. The method of claim 1 , further comprising:

retrieving a plurality of messages from the messaging service;

determining an order of the plurality of messages using timestamps of the plurality of messages;

determining a most recent message of the plurality of messages based on the order; and

reading the first number from the most recent message.

9. The method of claim 1 , further comprising:

receiving first data indicating a global positioning system (GPS) region associated with the vehicle;

receiving, from the first computing device, a current GPS location of the vehicle; and

determining that the current GPS location of the vehicle is within the GPS region, wherein the first control data is generated based at least in part on the current GPS location of the vehicle being within the GPS region.

10. A system comprising:

at least one processor; and

non-transitory computer-readable memory storing instructions that, when executed by the at least one processor, are configured to:

generate a first authentication code based at least in part on a first number in first data received from a first computing device of a vehicle, wherein the first computing device of the vehicle is associated with identifier data;

send a notification to a remote device;

receive a response to the notification from the remote device;

retrieve the first number from a messaging service based at least in part on the receiving the response to the notification;

generate a second authentication code using the first number

determine that the first authentication code matches the second authentication code;

determine rule data associated with the identifier data based at least in part on the first authentication code matching the second authentication code; and

send first control data to the first computing device of the vehicle based at least in part on the rule data, the first control data effective to prevent starting a motor of the vehicle.

11. The system of claim 10 , the non-transitory computer-readable memory storing further instructions that, when executed by the at least one processor, are further effective to:

determine, based at least in part on the rule data, at least one indicator bit stored in association with the identifier data; and

generate the first control data based at least in part on the at least one indicator bit.

12. The system of claim 10 , the non-transitory computer-readable memory storing further instructions that, when executed by the at least one processor, are further effective to:

receive, from a second computing device, instructions to change one or more inhibitor bits associated with inhibition of the motor of the vehicle;

receive, from the first computing device, a request to start the motor of the vehicle;

determine, using the rule data, that the one or more inhibitor bits indicate that starting the motor is permissible; and

send second control data to the first computing device, the second control data effective to permit starting the motor.

13. The system of claim 10 , the non-transitory computer-readable memory storing further instructions that, when executed by the at least one processor, are further effective to:

determine, based at least in part on the rule data, at least one indicator bit stored in association with the identifier data, the at least one indicator bit indicating that starting the motor of the vehicle is currently prohibited;

generate vehicle status data indicating that the starting the motor of the vehicle is currently prohibited; and

send the vehicle status data to the first computing device of the vehicle.

14. The system of claim 10 , the non-transitory computer-readable memory storing further instructions that, when executed by the at least one processor, are further effective to:

identify authentication credentials included in the response to the notification from the remote device, wherein the response is sent using a secure network communication protocol;

authenticate the remote device; and

retrieve the first number from the messaging service further based on the authentication of the remote device.

15. The system of claim 10 , the non-transitory computer-readable memory storing further instructions that, when executed by the at least one processor, are further effective to generate the first authentication code by inputting the first number into a hash function, wherein the first authentication code comprises a hash.

16. The system of claim 10 , the non-transitory computer-readable memory storing further instructions that, when executed by the at least one processor, are further effective to:

provide the first number to the messaging service; and

17. A method comprising:

receiving by a first computing device of a vehicle, a first request to start a motor of the vehicle;

in response to the first request:

sending identifier data to a remote computing device;

generating a first number; and

transmitting the first number to a cloud service to cause the cloud service to generate a first authentication code based at least in part on the first number, generate a second authentication code using the first number, determine that the first authentication code matches the second authentication code, and determine status data based at least in part on the first authentication code matching the second authentication code;
