Multi-factor authentication for vehicles

1. A method for controlling access to a vehicle, the method comprising:

receiving, at a vehicle authentication management server from a communication subsystem of the vehicle, a first request to authenticate a user requesting access to a first functionality associated with the vehicle;

sending, by the vehicle authentication management server to an electronic device associated with the vehicle, an instruction to perform, on the electronic device, a multiple-factor authentication of a first user of the electronic device based on one or more first authentication factors associated with the first functionality, wherein the instruction includes a requirement for the electronic device to evaluate at least the one or more first authentication factors;

receiving, at the vehicle authentication management server from the electronic device, a first message indicating that an identity of the first user of the electronic device has been verified based on at least the multiple-factor authentication; and

in response to receiving the first message, sending, by the vehicle authentication management server to the communication subsystem of the vehicle, a second message indicating successful authentication of the first user.

2. The method of claim 1 , wherein the one or more first authentication factors are identified based on retrieving, from a first database storing mappings of authentication factors to functionalities of the vehicle, those authentication factors that are associated with the requested first functionality.

3. The method of claim 1 , further comprising:

sending, to the first user, a verification code; and

confirming that the verification code was inputted to the electronic device, wherein the instruction to perform a multiple-factor authentication of the first user is sent to the electronic device in response to the confirming.

4. The method of claim 3 , wherein confirming that the verification code was inputted to the electronic device comprises receiving, from the electronic device, a confirmation message indicating that the verification code was inputted to the electronic device.

5. A method for controlling access to a vehicle, the method comprising:

receiving, at a vehicle authentication management server from an electronic device associated with the vehicle, a first request to access a first functionality associated with the vehicle;

sending, by the vehicle authentication management server to the electronic device, an instruction to perform, on the electronic device, a multiple-factor authentication of a first user of the electronic device based on one or more first authentication factors associated with the first functionality, wherein the instruction includes a requirement for the electronic device to evaluate at least the one or more first authentication factors;

receiving, at the vehicle authentication management server from the electronic device, a first message indicating that an identity of the first user of the electronic device has been verified based on at least the multiple-factor authentication;

verifying that the first user is authorized to access the vehicle; and

in response to the verifying, sending, by the vehicle authentication management server to a communication subsystem of the vehicle, a second message requesting the vehicle to grant access to the vehicle.

6. The method of claim 5 , wherein the one or more first authentication factors are identified based on retrieving, from a first database storing mappings of authentication factors to functionalities of the vehicle, those authentication factors that are associated with the requested first functionality.

7. The method of claim 5 , further comprising storing, in a second database, an association of the first user with the vehicle.

8. A system for controlling access to a vehicle, the system comprising:

a memory; and

a processor coupled to the memory, the processor being configured to:

receive, from a communication subsystem of the vehicle, a first request to authenticate a user requesting access to a first functionality associated with the vehicle;

send, to an electronic device associated with the vehicle, an instruction to perform, on the electronic device, a multiple-factor authentication of a first user of the electronic device based on one or more first authentication factors associated with the first functionality, wherein the instruction includes a requirement for the electronic device to evaluate at least the one or more first authentication factors;

receive, from the electronic device, a first message indicating that an identity of the first user of the electronic device has been verified based on at least the multiple-factor authentication; and

in response to receiving the first message, send, to the communication subsystem of the vehicle, a second message indicating successful authentication of the first user.

9. The system of claim 8 , wherein the one or more first authentication factors are identified based on retrieving, from a first database storing mappings of authentication factors to functionalities of the vehicle, those authentication factors that are associated with the requested first functionality.

10. The system of claim 8 , wherein the processor is further configured to:

send, to the first user, a verification code; and

confirm that the verification code was inputted to the electronic device, wherein the instruction to perform a multiple-factor authentication of the first user is sent to the electronic device in response to the confirming.

11. The system of claim 10 , wherein confirming that the verification code was inputted to the electronic device comprises receiving, from the electronic device, a confirmation message indicating that the verification code was inputted to the electronic device.

12. A system for controlling access to a vehicle, the system comprising:

a memory; and

a processor coupled to the memory, the processor being configured to:

receive, from an electronic device associated with the vehicle, a first request to access a first functionality associated with the vehicle;

send, to the electronic device, an instruction to perform, on the electronic device, a multiple-factor authentication of a first user of the electronic device based on one or more first authentication factors associated with the first functionality, wherein the instruction includes a requirement for the electronic device to evaluate at least the one or more first authentication factors;

receive, from the electronic device, a first message indicating that an identity of the first user of the electronic device has been verified based on at least the multiple-factor authentication;

verify that the first user is authorized to access the vehicle; and

in response to the verifying, send, to a communication subsystem of the vehicle, a second message requesting the vehicle to grant access to the vehicle.

13. The system of claim 12 , wherein the one or more first authentication factors are identified based on retrieving, from a first database storing mappings of authentication factors to functionalities of the vehicle, authentication factors that are associated with the requested first functionality.

14. The system of claim 12 , wherein the processor is further configured to store, in a second database, an association of the first user with the vehicle.
